Asimple ideal rankine cycle with water as the working fluid operates between the pressure limits of 4 mpa in the boiler and 20 kpa in the condenser and a turbine inlet temperature of 700°c. the boiler is sized to provide a steam flow of 50 kg/s. determine the power produced by the turbine and consumed by the pump.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
