Questions
Water is flowing in a river at 2 . The river is50 m wide and has an average depth of 5 m. The power available from the current in the river is (Density of water = 1000 kg )
detailed solution
Correct option is B
Power = Kinetic energy of water flowing per second= 12×area of cross-section × density ×(velocity)3= 12×50×5×1000×23W = 106W =1MWTalk to our academic expert!
