A rocket is to be launched from a launching pad and it is determined that the lifting force P is a function of its length l, mass m, diameter d, velocity
v, angle of attack θ, density of air ρ, viscosity of air μ, and speed of sound
of air a. Find the dimensionless π groups and rewrite the function in
terms of π groups.

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.

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
