AIPMT PRELIMS 2008 Physics Power MCQ Question
Type: MCQ-numerical-Medium-Class 11
Water falls from a height of 60 m at the rate of 15 kg/s to operate a turbine. The losses due to frictional forces are 10 % of energy. How much power is generated by the turbine ? (g = 10 m/s²)
A
12.3 kW
B
7.0 kW
C
8.1 kW
D
10.2 kW
Correct Answer
Option C
Detailed Explanation
The power generated is calculated using P = mgh(¹⁻loss), where m is mass flow rate, g is acceleration due to gravity, and h is height.
