A submarine running at full speed produces 14,500 shp with the propeller shaft spinning at 200 RPM. The reduction gear ratio is 15 with an efficiency of 94%. What is the torque on the propeller shaft? What speed are the turbines running? What is the power output by the turbines? If two turbines power the reduction gears and each has equal output, what is the torque output of one turbine? If the reduction gear losses go to the sub's lube oil system, what is the heat transfer to the lube oil (Btu/hr)?
