A steam turbine drives a ship’s propeller through an 8: 1 reduction gear. The average resisting torque imposed by the water on the propeller is 750 × 103mN and the shaft power delivered by the turbine to the reduction gear is 15 MW. The turbine speed is 1450 rpm. Determine
SOLUTION =14.235 MWThe net rate of working of the reduction gear= (15 – 14.235) MW= 0.7647 MW
