Question

Calculate the power of an electric motor that can lift 800 kg of water to store in a tank at a height of 1500 cm in 20 s. (g = 10 m / s^2)

Answer 1

Hey!

_________________________

Mass of water= 800 kg
Height of tank= 1500 cm = 150 m
Time= 20s
Gravity due to acceleration= 10 m/s^2

Power=?
P= mgh/t
P= 800×10×150/20
P= 60,000 W
P= 60 kW

Hope it helps...!!!

Answer 2

Power= mgh/t

Mass of load= 800kg
Height of tank = 1500 cm = 150 m
Time = 20s
g= 10 m/s^2

Power = mgh/t
P= 800×10×150/20
P= 60kW
