Explanation:
Engineers study the properties of fluids, including viscosity and compressibility, to test the efficiency of systems under given conditions. True or False?
Answer:
True.
Explanation:
The compressibility of a fluid can be defined as a measure of the change in volume (density) with respect to the amount of pressure applied to the fluid. Thus, as the pressure of a compressible fluid increases, both its viscosity and density increases.
Some examples of compressible fluids are vapors, gases, air etc.
Additionally, the compressibility of fluids plays a significant role in the field of science such as in aerodynamics, fluid mechanics, thermodynamics etc.
Viscosity can be defined as a quantity expressing the magnitude of internal friction that restricts the ease of flow between parallel layers at some distance apart having unit speed relative to each other.
These properties of fluids, including viscosity and compressibility are usually being studied by engineers such as civil engineers, in order to test the efficiency of systems under given conditions.

a poorly tighten terminal is often the cause of a/an ? a) open circuit b) circuit breaker interrupt c)short circuit d) ground fault
Answer: b) circuit breaker interrupt
Explanation:
Wires connect to outlets through terminals and these terminals need to be tight to ensure that electricity flows with the minimum amount of resistance.
If the terminal is poorly tightened, what happens is that resistance will build up as the appliance is being used and this resistance will make the terminal hotter.
The heat will continue to rise until the circuit breaker trips to interrupt the circuit and protect the appliance.
A process fluid having a specific heat of 3500 J/kg-K and flowing at 2 kg/s is to be cooled from 80 C to 50 C with chilled water, which is supplied at a temperature of 15 C and a flow rate of 2.5 kg/s. Assuming an overall heat transfer coefficient of 2000 W/m2-K, calculate the required heat transfer areas for the following exchanger configurations: (a) parallel flow (15 pts), and (b) counterflow (15 pts).

A two-position mode controller is used to control the water level in a tank by opening or closing a valve which in the open position allows water at the rate of 0.4 m3 / s to enter the tank. The tank has a cross-sectional area of 12 m2 and water leaves it at the constant rate of 0.2 m3 / s. The valve opens when the water level reaches 4.0 m and closes at 4.4 m. What will be the times taken for (a) the valve opening to closing, (b) the valve closing to opening
Answer:
The right solution is:
(a) 24 sec
(b) 24 sec
Explanation:
The given values are:
Water inlet's flow rate,
= 0.4 m³/s
Water outlet's flow rate,
= 0.2 m³/s
(a)
The volume of water filled will be:
= [tex]Area(height)[/tex]
= [tex]12(4.4-4)[/tex]
= [tex]12\times 0.4[/tex]
= [tex]4.8 \ m^3[/tex]
Opening to closing time taken will be:
= [tex]\frac{4.8}{0.2}[/tex]
= [tex]24 \ sec[/tex]
(b)
Inlet's flow rate,
= 0
Outlet's flow rate will be:
= 0.2 m³/s
Closing to opening time taken will be:
= [tex]\frac{4.8}{0.2}[/tex]
= [tex]24 \ sec[/tex]
a. The time taken for the valve opening to closing is 24 seconds.
b. The time taken for the valve closing to opening is 24 seconds.
Calculation of the time taken:a.
First we need to determine the volume of the water
= Area * height
= 12*(4.4-4)
= 12*0.4
= 4.8
Now the time taken should be
= 4.8/0.2
= 24 seconds.
b. The time taken should be
= 4.8/0.2
= 2.4 seconds

A flow of 2.6 MGD leaves a primary clarifier with a BOD of 131 mg/L. Determine the aeration period (hydraulic detention time) of an activated sludge tank that has a BOD loading of 35 lbsper 1000 ft3per day. Determine the sludge age of the facility given the following data: VSS concentration is 2100 mg/L, and the mass rate of wasted sludge is equal to 44 percent of the BOD loading.
Answer:
8.5 days
Explanation:
Given data :
Flow ( Q ) = 2.6 MGD = 11819.834 m^3/day
BOD = 131 mg/L
BOD loading rate = 35 Ibs/1000 ft^3 per day = 0.5606 kg/m^3/day
Calculate the sludge age of the facility
Given the BOD applied to the aeration tank = 11819.834 m^3/day * 131mg/l
= 1548.398 kg/day
first calculate the volume of the aeration tank
V = BOD applied / BOD loading rate
V = 1548.398 / 0.5606 = 2762.03 m^3
Hydraulic Detention time = V / Q
= 2762.03 / 11819.834 = 0.2336 day = 5.6 hour
next : determine the mass rate of the waste
= 44% * 0.5606 kg/m^3/day
= 0.2466 kg/m^2/day
finally determine the sludge age
= V * Xt / ∅w * R
= ( 2762.03 m^3 * 2100 * 10^-3 ) / ( 0.2466 * 2762.03 kg/day )
= 8.5 days

A 10 hp, 60 Hz, 2 pole, 440 volt (line-to-line), three-phase induction motor operates at 3240 rpm at the full load power output of 10 hp. (a) What is the mechanical synchronous speed in rad/sec and in rpm
Answer:
i. 3600 rpm ii. 377 rad/s
Explanation:
(a) What is the mechanical synchronous speed in rad/sec and in rpm
i. The mechanical synchronous speed in rpm
The mechanical synchronous speed in rpm, N = 120f/P where f = frequency = 60 Hz and P = number of poles = 2
So, N = 120f/P = 120 × 60 Hz/2 = 60 × 60 = 3600 rpm
ii. The mechanical synchronous speed in rad/s
We now convert N to rad/s by multiplying by 2π/60
So, the mechanical synchronous speed in rad/s , N' = 3600 rpm × 2π/60 = 60 × 2π = 120π rad/s = 377 rad/s

Air entrainment is used in concrete to: __________.
1. Strengthen the concrete
2. Increase the resistance of the concrete to freeze thaw damage
3. Create a better surface appearance
4. Make the concrete easier to handle during placement
5. Help evaporate excess water from the curing concrete
The answer is number 2) Increase the resistance of the concrete to freeze-thaw damage.
Air entrainment is used in concrete to Increase the resistance of the concrete to freeze thaw damage.
What is air entrainment?Microscopic air bubbles embedded in the concrete's surface reduce internal pressure by creating little spaces for water to expand into during freeze-thaw cycles.
Without these pockets, water has nowhere to escape, which causes concrete to crack and/or scale, severely reducing the lifespan of a structure. An air entraining additive, or AEA, is used to add air to the concrete mix.
To fit the requirements of the task at hand, a mix's air content can be changed. When pouring concrete in locations that experience freeze-thaw conditions, using air-entrained concrete is advantageous.
Therefore, Air entrainment is used in concrete to Increase the resistance of the concrete to freeze thaw damage.

The company PureNSafe is designing a portable, solar-powered disinfection system for Army use only. The system is simply an inlet pipe, a pump, a mixing chamber and an outlet pipe. The water is continuously pumped into the chamber where it is irradiated with UV light before it exits through the the appropriate tube into a collection vessel. The disinfection rate constant rate of disinfection with UV light is 7.80 s.1 and the amount of bacteria has to be reduced by 99.9%. be reduced by 99.9%. Since the Army requires an object that can be carried in a backpack, it requires that the chamber of the apparatus must not hold a capacity greater than 2 L. How much water will the system be able to produce during 10 hours of sunshine?
Solution :
The treatment system will operate as the well mixed chamber.
Disinfection rate constant for the UV light, k is 7.80 /s. Number of bacteria in water need to be reduced by 99.9%
Percent reduction of bacteria should be [tex]$(1-10^{0.99}) \times 100 =89.7\%$[/tex]
Volume of the unit chamber is fixed at 2L
Assume the inlet concentration, [tex]$C_0$[/tex] as 1000
The outlet concentration of bacteria, C should be [tex]$1000-\left(1000 \times \frac{89.7}{100}\right)$[/tex]
= 103
The well mixed chamber will then follow a completely mixed flow reactor model.
Compute the time required :
[tex]$t=\frac{1}{k}\left(\frac{C_0}{C}-1\right)$[/tex]
[tex]$t=\frac{1}{7.8}\left(\frac{1000}{103}-1\right)$[/tex]
= 1.115 s
Flow through the system is [tex]$\frac{2 \ L}{1.115 \ s}$[/tex] = 1.79 L/s
The amount of water treated during the 10 hours of sunlight is 1.79 x 10 x 60 x 60 = 64440 L

Consider a homogeneous, bare, spherical, source-free, critical, uranium-fueled reactor operating at a power Po. Explain how and why the power increases, decreases, or remains unchanged as a result of each of the separate changes to the reactor.
a. The reactor is deformed into the shape of a football (ellipsoid).
b. A person stands next to the core.
c. The temperature of the core is raised.
d. A neutron source is brought close to the core.
e. An energetic electron beam impacts the core.
f. The reactor is run at high power for a long time.
g. The core is launched into outer space.
h. A sheet of cadmium is wrapped around the core.
i. The enrichment of the fuel is increased.
Answer:
a) unchanged
b) unchanged
c) Increase
d) Increase
e) unchanged
f ) Increase
g) unchanged
h) decrease
i) unchanged
Explanation:
Determine how and why the power increases, decreases, or remains unchanged
a) The reactor been deformed will not cause an increase in power i.e. power remains unchanged and this is because power change/generated does not depend on dimension
b) No change will happen to the power ( Unchanged )
c) When the temperature of the core is raised the power increases and this is because of the increase in bombarding of particles causing an increase in charge particle
d) When a neutron source is brought close to the core the power will increase and this is because the presence of more neutron in the core results to an increase in energy released ( more power will be generated )
e) An energetic electron beam impacting the core will not cause an increase in power ( reason been that it is lighter than neutron ) power unchanged
f ) When the reactor is run at a high power there would be an increase in power generated
g) When the core is launched into outer space the power generated remains unchanged
h) when a sheet of Cadmium is wrapped around the core the power generated will be decreased ( reason : Cadmium can absorb neutrons thereby reducing reaction)
i) Increase in the enrichment of the fuel will not cause an increase in the power generated but it will sustain the reaction ( unchanged power )

Explanation:
The electrode therapy is not the most effective treatment for brain disorders because there are various other treatments which can treat the brain disorder without causing damage to the brain. electrode therapy greatly damaged the brain instead of treatment of brain disorder. Medication is the best way to treat brain disorder so that's why electrode therapy is not considered as the most effective treatment for brain disorders, and the doctors recommend an alternative treatment.
Polarization: Unpolarized light passes through three ideal polarizing filters. The first filter is oriented with a horizontal transmission axis, the second one has its transmission axis at 30° from the horizontal, and the third filter has a vertical transmission axis. What percent of the light gets through this combination?
Answer:
the percentage of light that gets through this combination is 9.38
Explanation:
Given the data in the question;
Let us represent the incident unpolarized light with [tex]I_0[/tex].
So, the amount of light intensity passing through the first polarizer will be;
[tex]I_1[/tex] = [tex]I_0[/tex] / 2 ------ let this be equation 1
An the amount of light intensity passing through the second polarizer will be;
[tex]I_2[/tex] = [tex]I_1[/tex]cos²θ
given that; the second one has its transmission axis at 30°
so, we substitute;
[tex]I_2[/tex] = [tex]I_1[/tex] × cos²( 30° )
[tex]I_2[/tex] = [tex]I_1[/tex] × 0.75
[tex]I_2[/tex] = 0.75[tex]I_1[/tex]
from equation; [tex]I_1[/tex] = [tex]I_0[/tex] / 2
[tex]I_2[/tex] = 0.75( [tex]I_0[/tex] / 2 )
[tex]I_2[/tex] = 0.375[tex]I_0[/tex] .
Now, the amount of light intensity passing through the third polarizer will be;
[tex]I_3[/tex] = [tex]I_2[/tex]cos² ( 90° - 30° )
[tex]I_3[/tex] = [tex]I_2[/tex] × cos²( 60° )
[tex]I_3[/tex] = [tex]I_2[/tex] × 0.25
we substitute
[tex]I_3[/tex] = 0.375[tex]I_0[/tex] × 0.25
[tex]I_3[/tex] = 0.09375[tex]I_0[/tex]
∴ [tex]I_3[/tex]/[tex]I_0[/tex] × 100 = 0.09375 × 100
⇒ 9.38%
Therefore, the percentage of light that gets through this combination is 9.38
