Assume that the reservoir is 200m deep, held back by the dam wall . A small horizontal pipe at the base of the dam transfers water to the generator hall, where it gushes out at high speed and is used to turn the turbines that generate electricity.
What are the main types of energy at the exit of pipe in turbine hall? PPE, KE, GPE, Part GPE and Part PPE, or Part KE and PPE
What is the speed of the water coming out of the pipe?
