Determine the average power of the pump, which delivers water with a volume of 4.5 meters

Determine the average power of the pump, which delivers water with a volume of 4.5 meters to a height of 5 meters in 5 minutes.

Determine the power by the formula

N = A / t,
Where
A – work to raise water,
t is time.

A = F * h,
here
F – strength,
h – lifting height.

F = m * g,
m is the mass of water,
g is the acceleration of gravity.

Let’s do the calculations

F = 4500 * 10 = 45000 H;
A = 45000 * 5 = 225000 J;
t = 5 * 60 = 300 s;
N = 225000/300 = 750 W.

Answer: the average pump power is 750 W.
