Question

Calculate power of a pump which can lift 70 kg of water through a vertical height of 16 meters in 10 seconds and also find the power in horse power
​

Answer 1

Answer:

Power is energy/time

energy = mgh

m = 70 kg

g = 10 m/s^2

h = 196 m

time = 10 s

power = 70*10*196/10

Power = 13720 J/s or 13720 W

Answer 2

Answer:

1120Js or 1.5 horse power

Explanation:

P=?

m=70kg

t=10s

d=16m

g=10

Formula

P= work done/time   ; work done = FXS

P=FXS/t       ; F=ma    ;  a=g

P=mgs/t

P=70X10X16/10

1120Js

horse=1120/746

horse power = 1.5h
