An equimolar mixture of helium and argon gases is to be used as the working fluid in a closed-loop gasturbine cycle. the mixture enters the turbine at 1.6 and 1500 k and expands isentropically to a pressure of 200 determine the work output of the turbine per unit mass of the mixture

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.
