Fluid momentum problems are solved with the aid of both free body diagrams and control volumes of such problems. explain, list or define tems which would be included on each of the two diagrams required, and describe or show features common to both diagrams. why are these two drawings typically required and kept separate?

Fluids at rest possess no flow energy. a)- true b)- false

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.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
