Problem 3.052 a piston–cylinder assembly contains 2 lb of water, initially at 100 lbf/in.2 and 600°f. the water undergoes two processes in series: a constant-pressure process followed by a constant volume process. at the end of the constant-volume process, the temperature is 300°f and the water is a two-phase liquid–vapor mixture with a quality of 40%. neglect kinetic and potential energy effects. determine the work and heat transfer for each process, all in btu.

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
