An ideal gas goes through an expansion process where the volume of the gas doubles. which process will lead to a larger work output, an isothermal process or a polytropic process with n = 1.25?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

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.
