Question

Water from a stream is falling on the blades of a turbine at the rate of 100 kg/sec. If the height of the stream is 100 m, then the power delivered to the turbine is -

• A. 100 kW
• B. 100 W
• C. 10 kW
• D. 1 kW

Answer 1

Answer: (A)

100 kW

Answer 2

P = $\frac { \mathrm { dm } } { \mathrm { dt } }$gh = 100 × 10 × 100

= 100 kW

[P = $\frac { \mathrm { dm } } { \mathrm { dt } }$gh = 100 × 10 × 100

= 100 kW]
