Answer: valving the pump discharge to reduce the flow will only result in an increase in the water velocity according to the laws of continuity of flow.

Q = AV = constant.

The pump speed of 150 gpm is, and will remain constant. Valving simply reduces flow area A, which is balanced out by increased velocity V of water through the pipe.

This does not affect the pump speed Q (flow rate) and hence it remains the same.

A single-cylinder pump feeds a boiler through a delivery
Studentka2010 [4]

Answer:

Net discharge per hour will be 3.5325 m^3/hr

Explanation:

We have given internal diameter d = 25 mm

Time = 1 hour = 3600 sec

So radius r=\frac{d}{2}=\frac{25}{2}=12.5mm=12.5\times 10^{-3}m

We know that area is given by

A=\pi r^2=3.14\times (12.5\times 10^{-3})^2=490.625\times 10^{-6}m^2

We know that discharge is given by Q=AV, here A is area and V is velocity

So Q=AV=490.625\times 10^{-6}\times 2=981.25\times 10^{-6}m^3/sec

So net discharge in 1 hour = 981.25\times 10^{-6}m^3/sec\times 3600=3.5325m^3/hour

How do you take a picture
Mrrafil [7]
to take a picture just choose “take photo” on the button next to the keypad, if you are on a computer it’s the same thing if your computer has a video screener or whatever they call it but if not I’m not sure, hope this helps!
