In a flow of air between parallel plates spaced 0.03 m apart, the centerline velocity is 1:2m=s and that 5 mm from the pipe wall is 0:8m=s. Assuming laminar flow, determine the wall shear stress using each of the measurements. Explain whether the flow is laminar or turbulent.

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

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

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.
