Question 24: NCERT Solutions for 12th Class Physics: Chapter 7-Alternating Current
At a hydroelectric power plant, the water pressure head is at a height of 300 m and the water flow available is 100 m3s-1. If the turbine generator efficiency is 60%, estimate the electric power available from the plant (g = 9.8 ms-2).
Solution:
Work done by liquid pressure = pressure x volume shifted power of flowing water
