Arigid tank initially contains 1.4 kg saturated liquid water at 200◦c. at this state, 25 percent of the volumeis occupied by water and the rest by air. now heat is supplied to the water until the tank contains saturatedvapor only. determine (a) the volume of the tank, (b) the finaltemperature and pressure, and (c) the internalenergy change of the water.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
