If water falls from a dam into a turbine wheel 20 metre below, then find the velocity of water at the turbine Share with your friends Share 0 Mousam Maity answered this Dear Student, Answer to your question is given below: Given, height of the dam, h = 20 macceleration due to gravity, g = 10 m/s2During the fall the Potential Energy gets converted to Kinetic Energy,Potential Energy, PE = mghand Kinetic Energy, KE = 12mv2By the conservation of total mechanical energy,KE= PE⇒ 12mv2 = mgh⇒ v2 = 2gh⇒ v2 = 2× 10 × 20⇒v = 400⇒v = 20 m/sThe velocity of water at the turbine is 20 m/s.
