Randall D. Knight โ Work and Kinetic Energy: Problem 61
A hydroelectric power plant uses spinning turbines to transform the kinetic energy of moving water into electric energy with 80% efficiency. That is, 80% of the kinetic energy becomes electric energy. A small hydroelectric plant at the base of a dam generates 50 MW of electric power when the falling water has a speed of 18 m/s. What is the water flow rateโkilograms of water per secondโthrough the turbines?
๐ Solution Approach
Given: . A, 50 MW, 18 m
