In a trial run, the De Laval steam turbine at Oman Power Plant rotates at 3000 rpm. The steam is issued from the nozzle at 400 m/s and the nozzle angle is 20o. The blade speed ratio is 0.41and the friction loss in the blade channel is 15%of the kinetic energy corresponding to the relative velocity at the inlet to the blades.

Also, how would you determine the size of the turbine wheel required? Draw a suitable velocity diagram.
