steam flowing at a rate of 16 kg/s expands through a turbine operating at staedy state. The rate of transfer out of the turbine is 600 kW. The steam enters at 2 MPa, 320 C and exits to the atmosphere at 80 kPa and a quality of 0.7, neglecting the cahnge of kinetic and potential energy. Determine: the exit temperature in C.

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.
