An unknown refrigerant is used in a refrigerator. A saturated mixure of 30 per cent quality exits the expansion valve at 1 bar pressure, at a temperature of -30 degrees C, and enters the evaporator. The refrigerant exiting the evaporator is saturated vapor with a specific volume of 0.2 m^3/kg. Assume the specific volume that saturated liquid would have for this refrigerant is zero. A laboratory test shows that the saturation pressure at -31 deg C is 0.9 bar and the saturation pressure at -29 deg C is 1.1 bar. If the mass flow rate of refrigerant is 0.01 m^3/s, find the refrigeration capacity in kW.
