It has been given that:
15 gallons per minute are the water's volumetric flow rate.
The pipe that exits the pump has a 1 inch diameter.
(a) When the diameter of the pipe that leaves the pump is 1 inch, flow work is done by the water as it leaves the pump and enters the pipe will be
W= 7133.2ft.lbf / min
Here, measuring the amount of work flow performed by the water as it exits the pump and enters the pipe is the goal.
The relation can be used to express the work flow that is supposedly complete:
W = P × V
where;
Pressure is P.
Volume is V.
The gauge pressure is included in the specified outlet pressure.
Now, the relation may be used to express the pressure in the pump P:
[tex]P_{absolute}[/tex] = [tex]P_{gauge}[/tex] + [tex]P_{atmospheric}[/tex]
[tex]P_{absolute}[/tex] = 10 psig + 14.7 psig
[tex]P_{absolute}[/tex] = 24.7 psig
W = P × V
W = 24.7 psig × 15 gal/min
W = (24.7 psig * [tex]\frac{\frac{lb_{f} }{in^{2} } }{psig}[/tex] ) * (15 [tex]\frac{gal}{min}[/tex] * [tex]\frac{0.1337 ft^{3} }{1 gal}[/tex] * [tex]\frac{144 in^{2} }{1 ft^{2} }[/tex] )
W = 7133.2 [tex]\frac{ft. lb_{f} }{min}[/tex]
This means that the water is stated to produce work at a rate of flow of
W= 7133.2 [tex]\frac{ft.lb_{f} }{min}[/tex]
(b) Work done by the water as it leaves the pipe and enters the pool is:
According to the obtained data:
Through a 1.5-inch-diameter aperture, the pool's water is refilled.
when there is 1 atm of pressure.
The water then exerts the following amount of energy when it exits the pipe and enters the pool:
W = P × V
W equals 1 atm x 15 gal/min.
W = 1 atm * (15[tex]\frac{gal}{min}[/tex] * [tex]\frac{0.1337 ft^{3} }{1 gal}[/tex] * [tex]\frac{144 in^{2} }{1 ft^{2} }[/tex])
W = 4245.24 [tex]\frac{ft.lb_{f} }{min}[/tex]
When a result, the water's work rate as it exits the pipe and enters the pool is at W = 4245.24 [tex]\frac{ft.lb_{f} }{min}[/tex]
(c) Due to the fact that the data provided for the flow rate and pressure do not account for changes in time in the space between the pump and the pool, we may say that the system is in a steady state.
However, the main reason why the system is out of equilibrium is that:
As indicated in the inquiry, the pressure coming out of the pipe is different from the pressure of the water at the pool's surface.

give three examples of planetary changes that are predicted to occur (or are already occurring) as a result of this seemingly small amount of warming.
Sea ice loss, glacier and ice sheet melting, sea level rise are the planetary changes that are predicted to occur.
What is causing climate change?Since the Industrial Revolution, human activities have contributed significantly to the atmospheric release of carbon dioxide and other greenhouse gases, altering the planet's climate. The earth's climate is also influenced by natural processes like variations in the sun's energy and volcanic eruptions.
according to scientists' predictions of the long-term effects of climate change.
CO2, nitrous oxide, methane, chlorofluorocarbons, and water vapor are examples of greenhouse gases. Although the Sun has contributed to past climate changes, the evidence indicates that the Sun cannot be the cause of the current warming.

In 1909, scientist ernest rutherford directed a stream of high speed alpha particles at a thin piece of gold foil. Some of the particles passed through, some were deflected, and some bounced straight back. This result caused rutherford to conclude that.
Rutherford considered these observations and he concluded: The fact that most alpha particles went straight through the foil is evidence for the atom being mostly empty space. A small number of alpha particles being deflected at large angles suggested that there is a concentration of positive charge in the atom.
What is an atomic nucleus ?Protons, which have a positive charge, and neutrons, which have no electrical charge, make up the nucleus. On the basis of the 1909 Geiger-Marsden gold foil experiment, Ernest Rutherford identified the atomic nucleus in 1911,which is the compact, dense region made up of protons and neutrons at the heart of an atom. The electron cloud contributes very little to the atom's mass, which is almost entirely in the nucleus. The nuclear force brings protons and neutrons together to create a nucleus.To learn more about : nucleus

an adiabatic compressor compresses air at 150 kpa and 400k to 2 mpa. what is the exit temp of the air if it is an isentropic process
The exit temperature = 5333.33 K
Explanation:The inlet pressure: P₁ = 150 kpa
The inlet temperature T₁ = 400K
The exit pressure, P₂ = 2 MPa = 2000 kPa
The exit tenperature, T₂ = ?
The relationship between temperature and pressure for an isentropic process is shown below

Difference between digital meter and analogue meter
If you answer I will give 100 points!
Answer:
Digital meter is the one which take the input in one form and should output in digital form like in numbers or by any other electronic means where as the analogue meter is the one which uses some mechanical method to display the output like deflection of the needle etc.

The most significant difference between analog and digital instruments is in their type of output method, i.e., an analog instrument shows the output by the deflection of pointer on a scale, whereas a digital instrument shows the output on a digital display screen in the form of text or numbers
based on the figure 2-1, which substances would become solid at 10 degrees celcius?
The substance that we can from the table that would be solid at a temperature of 10 degrees Celsius is known as acetic acid.
What is the substances that would become solid at 10 degrees Celsius?We know that the temperature is the degree of the hotness or the coldness of a body. More appropriately, we define the temperature of a body as the average kinetic energy of the molecules of a body. One of the most effects that the temperature of the body could have is that when the temperature is increased or decreased, there could be a change of state of the body.
This implies that the state of matter that we can find a particular object at a given time would depend heavily on the temperature of the substances. Generally, the state of matter than a material is found is quoted mostly with reference to room temperature.
