Calculating the carbon footprint is difficult because of a lack of knowledge of all the factors of carbon emission on land.

Imagine drinking concentrated orange juice endlessly. because surely this is the best way to lose weight. Orange juice is recommended in moderation, but doctors are not the first to recommend it to people trying to lose weight.

Just as we don't want people to believe that more orange juice is the solution to the obesity pandemic, we don't want people to believe that the best way to fight climate change is to recycle more.

Recycling and blackouts are great steps towards a more sustainable society, but nothing is more important to the climate than reducing meat consumption, air travel, and driving.

People with good intentions often make the wrong decisions when it comes to reducing their carbon footprint.

For example, a test was conducted in which participants were selected and then the participants were then presented with 15 behaviors and asked to classify the behavior as low, medium, or high (with low representing less than 1% of a person's carbon footprint and high representing more than 5%).

The first calculation is the  per phase line to node voltage.

= 2200√3 / √3

= 2200 V

Next is three-phase complex power absorbed by load 1

560 x 10³ ∠cos-1(0.707)

= 560 x 10³∠45

Then we would have

(396 + j396)kva

We have S2 = 132kva

next is the total complex load calculation

(396 + j396 + 132)kva

= 528 + j396 kva

= 660 ∠36.87 degrees kva

total current that is in the line

= 660 x 10³ ∠-36.87 / 3 x 2200

= 100 ∠ -36.87 degrees kva

Using the voltage law of Kirchoff

E1 = E2 + ZLI

= (2200 + 0.4 + j2.7)100 ∠ -36.87

= 2200 ∠0 + (2.73 ∠ 81.57)(100 ∠ -36.87)

b. Total real and reactive loss

= 3 x (.4 + 2.7j)(100 x100)

= 12 + 81 j

find the real power loss

p = 12 kw

total power loss is 12 kw

The reactive power loss is 81 Kvar

c. total 3 phase power

2401.7∠4.58 and 100∠36.87

= 3(2401.7∠4.58  x  100∠36.87)

It should be noted that from the information, the oil that is transported on a day = 500000 bbl. Based on the information given, this is equal to 79491.256 cubic meter.

It should be noted that the flow rate will be calculated as:

= Oil transported / Time taken

= 0.92m³ per second

It should be noted that the area will be calculated as:

A = πr²

where

π = 3.14

r = radius = Diameter / 2 = 0.76/2 = 0.38

Area = πr² = 3.14 × (0.34)² = 0.45m²

A performance (HC) curve for a given centrifugal pump shows that option B. Flow rate decreases as the head required to overcome system resistance increases.

The Centrifugal pump curves are helpful because they display metrics for the performance of the pump based on the head (pressure) the pump produces and the water flow through the pump. Impeller diameter, head, as well as the pump speed all affect flow rates.

Note that an instrument that predicts a pump's head and flow performance is a centrifugal pump performance curve. Pumps provide low volume flow rates when pumping against high-pressure heads and high volume flow rates if they are said to be pumping against low-pressure heads.

Therefore, one can say that every centrifugal pump has a curve that it follows in order to function, and every curve has a start point (the shut-off or zero flow) and an end point (the end-of-curve or the maximum flow that can be achieved without overtaxing the motor).

A non-rotating solid round bar with diameter of 2-in has a groove cut to a diameter of 1.8-in, with a groove radius of 0.1-in. the bar is loaded with a repeated bending load that causes the bending moment at the groove to fluctuate between 0 and 25000 lbf-in. the bar is hot-rolled aisi 1095, but the groove has been machined. The factor of safety guarding against first-cycle yielding will be nf=1.11 and the factor of safety against fatigue failure will be ny=2.41.

From the table A-20 Deterministic ASTM minimum tensile and yield strengths for HR and CD steels, we have approximately:

D= 2.1, d (diameter) = 1.892, r= 0.117

Endurance limit for the material= Se'= 60 kpsi

According to the goodman relation= nf= 0.833

Yielding factor of safety: ny= Sy/σmax= 66/36.828

ny= 1.792

When the factor of safety is 1, the substance is practically at yield. Based on the greatest anticipated load situation, the majority of designers aim for a safety factor of between 2 and 4. Unless the maximum expected load is repeatedly applied, if some design elements experience yield, part failure is not necessarily the result.

The element of safety with regard to a fatigue failure at a specific design life is known as the fatigue safety factor. The Factor of Safety can go up to 15. Values less than one for the Fatigue Safety Factor imply failure before the design life is achieved.

An estimate of the safety factor of the shaft is 1.10

We have the following:

Torque=230nm

Yield compression=170mpa

To estimate the safety factor of the shaft, we will have to find first the following:

Maximum shear stress:

Shear stress=[tex]\frac{16T}{\pi d^{3} }[/tex]

                   =    [tex]\frac{16*230}{\pi *(25mm*\frac{10^{-3}m }{1mm})^{3} }[/tex]

                   =75MPa

We, now get the principle stress:

σ[tex]_{1}[/tex]=75MPa

σ[tex]_{2}[/tex]=-75MPa

The torsional yield strength:

Torsional yield strength=(yield strength in tension*yield strength in compression)/(yield strength in tension +yield strength in compression)

                                   =(160*170)/(160+170)

                                  =82.4MPa

Now, we can calculate the factor of safety using this given relation:

Factor of safety=(Torsional yield strength/Maximum shear stress)

                         =82.4MPa/75MPa
