Question
A Francis turbine runner is to be designed for the following data:
Net head = 50 m, shaft power = 400 kW, speed = 450 rpm, hydraulic efficiency = 85%, overall efficiency = 80 %, flow ratio = 0.15, breadth and dia ratio = 0.1.
Assume the inner dia as one half the outer dia. The velocity of flow is constant throughout. The discharge is radial. Neglect vane thickness.
