Hi all!
How do we define the power of a pump?
I read a formula from a book which defines the power of the pump as follows:
Power of the pump = Maximum back pressure * maximum flow rate / 2
Can anyone explain why the right hand side equals the left hand side?
I don't understand why the LHS is divided by a factor of 2.
And, is the power of a pump always the same value, no matter at any flow rate/back pressure?
It seems to be that at maximum back pressure, the flow rate is zero and the pump power is zero then?
Please help.
