turbine at a rate of 100 kg/s from a certain spring.If the height of the spring be 100 metres, the power transferred to the turbine will be:
A .
100 kW
B .
10 kW
C .
1 kW
D .
1500kw
m=100 kg
Height=100 m
w=mgh
⇒w=100×10×100=105 J
Power=TimetakenWorkdone
⇒Power=1105
⇒Power=105 W
⇒Power=102×103 W=102 kW
