A reaction turbine works at 500 r.p.m. under a head of 100 m. The diameter of turbine at inlet is 100 cm and flow area is 0.35 m2. The angles made by absolute and relative velocities at inlet are 15 and 60 respectively with the tangential velocity. Determine : (i) The volume flow rate, (ii) The power developed, and (iii) Efficiency. Assume whirl at outlet to be zero.
