Question

an electric pump has 2KW power. How much water will the pump lift every minute to a height of 10m ?​

Answer 1

1200

Step-by-step explanation:

p=w/T

w=F. d

2000watt=F. d/60

F=12000N

F=mg

m=12000/10=1200kg

Answer 2

Answer:

Data : P=2kW = 2000 J/s, t = 60s,

h = 10m, g = 9.8 m/s², m = ?

P = W mgh

___ = ____

t t

= m = pt 2000 J/s × 60s

__ = ____________

gh 9.8 m/s² × 10m

=12000

______ kg = nearly 1224 kg

9.8

This gives the required mass of water.
