volume=30000litre=30m3
h=45m
t=10min=10*60=600sec
w=?
p=?
w=mass*distance
=(density*volume)*distance
=1000*30*45
=1350000joule
p=w/t
=1350000/600
=2250j/s
kingkayabkhan1975:
work done is equal to force into displacement not mass into displacement
work done is equal to force into displacement
and the correct answer is 13230 000

given= water pump pump = 30,000 litres of water i.e 30000/1000, 30 m*3
height= 45 meters
time=10 min i.e 600 sec
density of water=1000kg/m*3
:mass= volume×density
mass =30m*3×1000kg/m*3
mass=30000 kg
work done = mgh [ work done against Gravity]
w=30000kg×9.8m/s*2×45m
w= 13230000joules
power= work done/time
power= 13230000/600
power =22050 watts
