Very nice explanation, flowrate should not be put in the list like "given" , it's the theoretical demand for that specific scenario, given term sounds like it's a reading from the design

Nice video. But this only dealt with the head of the pump. This did not deal with the length of the pipe that the pump has to flow the water through. How can we include the length of the pipe as well.

The diameter of pipe looks too small for that required flow since the calculated velocity is too high!

The vertical distance between fluid surface and pump intake is sometimes called suction head. So don't you also need to know the elevation of the pump intake to make sure your pump suction head is sufficient? Thanks.

Elevation at suction is 150M, Elevation at Discharge is 200M, Length of the pipe is 300M ???

@7:18 you state "16.9m of friction loss"... should be 13.9m of friction loss and 3.0m to account for fluid velocity dynamic head..." that the pump has to overcome :)

Hi, does the pump elevation matters? Or are we assuming the pump is installed at 150m ish? But 300m away from the pool?

Most of the time you can ignore suction height because when you're dealing with altitudes in the 100s of meters, a few cm really don't amount to much.

I hate how they always start with given information and then jumps into calculation. Why not to make it real life and start with a scenario, explain the situation and then start calculation like you would do in real life. I have seen similar examples through out 4 years of schooling, in real life they are garbage... zero value.

I think there is a mistake in the static head calculation. If you take the datum point at pump line, 150 m will be minus and 200 is positive, total static head will be 350 m.

he used pi/4 so its correct to square the diameter. Area=(pi/4)(d^2) or Area= pi*r^2😊 Agree?
