Question

Calculate the power of a pump in watts required to lift 160kg of water through a vertical height of 3m in 30 seconds. ( g = 10 m/s^2)

Answer 1

Given :-

Mass= 300kg

Height = 20m

Time = 20sec

Required:-

Power =?

P=W/t

W=FS

So.....

P= FS/t

F=mg

So .....

P= mgh/t

hope it helps you

P= 300 × 10 ×20 / 20

P = 3000Watt

Answer 2

Answer:

1600watt

Explanation:

force= m×g

f= 160×10=1600

work done = force×time

w= 1600×3=4800

power =workdone/time

p=4800/3 = 1600watts
