1- A fixed mass rigid tank is filled with Refrigerant-134a. Assuming initially, R-134a is under 160 psia and saturated condition (quality, x, = 1.0). The volume of tank is 20 ft. Then it went through a process until the final pressure, P, reduced to 50 psia, and the heat transfer occurred during this process. Determine (a) the final temperature, (b) the amount of R-134a been condensed, (c) the net heat transfer. (15 points)
A rigid tank contains a partition that divides the tank into two sections, each having a volume of 2 ft3 . The left side contains 1.5 lbm of refrigerant R-134a at a pressure of 50 psia, and the right side contains 4 lbm of refrigerant R-134a at 30 psia. The partition is removed and the contents are allowed to mix. Heat transfer occurs with the surroundings until the entire tank contents reach a new equilibrium temperature of 60 °F. For...
A 0.7-m3 rigid tank contains refrigerant-134a initially at 160 kPa and 40 percent quality. Heat is now transferred to the refrigerant until the pressure reaches 600 kPa. Determine the amount of heat transferred.
A 0.145 m rigid tank initially contains refrigerant-134a at 1 MPa and 100 percent quality. The tank is connected by a valve to a supply line that carries refrigerant-134a ad.2 MPa and 36°C. Now the valre is opened, and the refrigerant is allowed to enter the tank. The valve is closed when it is observed that the tank contains saturated liquid atl.2 MPa. Determine (a) the mass of the refrigerant that has entered the tank 156.057g(Kound to three decimal places)...
Saturated vapor refrigerant R134a is stored at 20 psia and has a volume of 2.2781 ft3/lbm. The quality of the R134a is what value?
Five lbm/min of Refrigerant 134a enters a water-jacketed compressor as a saturated vapor at 10 psia and is discharged at 140 psia, 120°F. The power supplied to run the compressor is 10 HP. Cooling water enters the water-jacket at 70°F and leaves at 100°F. Determine the mass flow rate of the cooling water.
Problem 3.034 A closed, rigid tank is filled with water. Initially, the tank holds 1.0 lb of saturated vapor and 6.0 lb of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. Kinetic and potential energy effects can be ignored. Determine the volume of the tank, in ft3, the temperature at the final state, in °F, and the heat transfer, in Btu. ? Step 1 KI Your answer is incorrect. Try again. Determine...
An insulated rigid vessel contains 5kg of saturated liquid-vapor mixture of Refrigerant- 134a at 200kPa. At this stage, one-fifth of the mass is in vapor phase and rest is in liquid. Now using an electrical resistance heater, heat is supplied to the contents of the vessel until all of the refrigerant is converted to saturated vapor. Show this process on a P v diagram with respect to saturation lines and determine, 1. volume of the rigid vessel 2. temperature, in...
