Question

a motor pump is rated 10 hp. calculate the volume of water that it will pump out from a of 300 m in one hour. [take 1 hp = 750 w and density of water = 1000kg m ?] depth​

Answer 1

Answer:

Depth = d = 20 m

H = 10 + 20 = 30 m

Volume = V = 2238 l

Mass of water = m = m=density×volume=1kg/m
