Question

he velocity of steam, leaving the nozzles of an impulse turbine, is 1300 m/s and the nozzle angle is 25°. The blade velocity is 375 m/s and the blade velocity coefficient is 0.78. Assuming no loss due to shock at the inlet, calculate for a mass flow of 0.5 kg/s and symmetrical blading : i) Blade inlet angle ii) Driving force on the wheel iii) Axial trust on the wheel iv) Power developed by the turbine.

Answer 1

Answer:

Nozzle Efficiency calculator uses nozzle_efficiency = Change in Kinetic Energy/Kinetic Energy to calculate the Nozzle efficiency, Nozzle Efficiency is the efficiency with which a nozzle converts potential energy into kinetic energy, commonly expressed as the ratio of the actual change in kinetic energy to the ideal ...
