A one-fifth scale model of a water turbine is tested in a laboratory at T = 20C.
Question:
A one-fifth scale model of a water turbine is tested in a laboratory at T = 20°C. The diameter of the model is 8.0 cm, its volume flow rate is 25.5 m3/h, it spins at 1500 rpm, and it operates with a net head of 15.0 m. At its best efficiency point, it delivers 720 W of shaft power. Calculate the efficiency of the model turbine. What is the most likely kind of turbine being tested?
