aturated liquid from condenser Prond = 900 kPa ricond =0.05 kg/s refrigerant to compressor ank 500 kPa Başka yonergeler almak için tıklayın Figure illustrates a vapor separator that is part of a refrigeration system. Saturated liquid R134a leaves the condenser at State 1 with a mass flow rate of 0.05 kg's and pressure of 900 kPa. This refrigerant enters the vapor separator (a large, insulated tam through a valve. The pressure in the tank is 500 kPa. There is no pressure drop due to flow through the tank (ie, the pressure at States 2, 3, and 5 are all the same). The flow at State 2 is two-phase. The liquid portion of this flow falls to the bottom of ti tank due to gravity while the vapor portion remains at the top. The saturated liquid is drawn from the bottom of the tank (at State 3). The saturated vapor is drawn off of the top of the tank at State 5 and fed to a compressor Assume that the vap separator is adiabatic, rigid, and operating at steady state. a) The quality of the refrigerant at State 2 is b) The mass flow rate of refrigerant at State 3 is kg/s and the mass flow rate of refrigerant that goes to the compressor is kg/s c) The entropy production of the vapor separator is kw/K

Figure illustrates a vapor separator that is part of a refrigeration system. Saturated liquid R134a leaves the condenser at State 1 with a mass flow rate of 0.05 kg/s and pressure of 900 kPa. This refrigerant enters the vapor separator (a large, insulated tank)
through a valve. The pressure in the tank is 500 kPa. There is no pressure drop due to flow through the tank (i.e., the pressure at States 2, 3, and 5 are all the same). The flow at State 2 is two-phase. The liquid portion of this flow falls to the bottom of the
tank due to gravity while the vapor portion remains at the top. The saturated liquid is drawn from the bottom of the tank (at State 3). The saturated vapor is drawn off of the top of the tank at State 5 and fed to a compressor. Assume that the vapor
separator is adiabatic, rigid, and operating at steady state.
a) The quality of the refrigerant at State 2 is
b) The mass flow rate of refrigerant at State 3 is
kg/s and the mass flow rate of refrigerant that goes to the compressor is
kg/s.
c) The entropy production of the vapor separator is
kw/K
