In the refrigeration experiment, the following values were measured when using the TXV valve (the TXV valve has been calibrated for a superheat temperature of 5C)°: 1- Temperature at the compressor outlet: 94.7±0.5°c 2- Absolute pressure at the valve inlet: 1150± 40 kPa 3- Absolute pressure at the valve outlet: 260± 10 kPa What is the error in the enthalpy of the refrigerant leaving the condenser in units of kJ/kg? Use at least 2 significant digits when you fill in your answer. NOTE: Assume that the quality at the exit of the condenser is exactly zero with no error.

Question
In the refrigeration experiment, the following values were measured when using the TXV valve (the TXV
valve has been calibrated for a superheat temperature of 5C)°:
1- Temperature at the compressor outlet: 94.7±0.5°c
2- Absolute pressure at the valve inlet: 1150± 40 kPa
3- Absolute pressure at the valve outlet: 260± 10 kPa
What is the error in the enthalpy of the refrigerant leaving the condenser in units of kJ/kg? Use at least 2
significant digits when you fill in your answer.
NOTE: Assume that the quality at the exit of the condenser is exactly zero with no error.
Answer: 2.0
