Question

an electric pump has 2kw power. how
much water will the pump lift every minute to a height of 10m
Ans:power=2kw =2*10w
time=1minute=60 second
height=10m
p=w\t=mgh\t
2*10=(m*9.8*10/60
m= 2*10*60/9.8*10
m=1224.5kg.​

Answer 1

Answer:

Mass is 1224.4898 kg

Step-by-step explanation:

power = 2kW = 2000 W

time = 1minute = 60 sec

height = 10m

work done / time = power

=> mgh / t = 2000

=> m × 9.8 × 10 / 60= 2000

=> m × 98 / 60 = 2000

=> m = 2000/98 × 60

=> m = 1224.4898 kg
