A 0.1-m3 rigid tank contains saturated liquid-vapor mixture of water, initially at 150 kPa and 52 percent quality. Heat is now transferred to the tank until the system becomes superheated vapor and the pressure reaches 300 kPa. Determine (a) the total mass of the mixture in the tank and (b) the amount of heat transferred.

A 1.2 m3 rigid tank initially contains steam at 8 MPa and 400 ◦C. The steam slowly comes out through a hole at the bottom until the pressure drops to P0 while keeps the temperature constant. Making the pertinent considerations determines: a) the heat transferred, in kJ when P0 = 2 MPa. b) graph the heat transfer, in kJ, versus P0 from 0.5 to 8.0 MPa

A rigid tank, with a volume of 25 L, contains nitrogen at 355 K and 1.2 MPa. The tank is then cooled to 120 K. What work has been done and the heat transferred in this process? Data: Cv = 0.745 kJ/kgK, Cp = 1.042 kJ/kgK, MM(N2)=28 g/mol, R = 8.314 m^3 Pa/molK. Use the ratio PV = nRT to determine the amount of nitrogen contained in the tank.

A rigid tank has a volume of 0.01 m3. It initially contains saturated water at a temperature of 200 oC and a quality of 0.4. The top of the tank contains a pressure regulating valve which maintains the vapor at constant pressure. This system undergoes a process where it is heated until all the liquid vaporizes. How much heat in (kJ) is required? You may assume there is no pressure drop in the exit line.

A hole develops in the wall of an initially-evacuated, rigid tank of volume 1.5 m3 . The hole allows propane from the surroundings to flow into the tank at a pressure of 1 bar and a temperature of 5⁰ C until the pressure inside the tank reaches 1 bar. Heat transfer between the tank and the surroundings is negligible. Determine the final temperature in the tank in ⁰C and the final mass contained inside the tank in kg. Do Not...
