Question

Refrigerant-134a enters a compressor at 180 kpa as a saturated vapor with a flow rate of 0.35 m³/min and leaves at 700 kpa. The power supplied to the refrigerant during the compression process is 2.35 kW. What is the temperature of R-134a at the exit of the compressor?

Answer 1

To find the temperature of R-134a at the exit of the compressor, we can use the ideal gas law and the specific heat capacity of R-134a.

Step-by-step explanation:

To find the temperature of R-134a at the exit of the compressor, we can use the ideal gas law which relates pressure, volume, temperature, and the number of moles of gas. In this case, we are given the pressure and flow rate of the refrigerant, as well as the power supplied during the compression process.

Using the ideal gas law, we can calculate the number of moles of R-134a. Then, we can use the specific heat capacity of R-134a to determine the change in temperature during compression.

Finally, we can add the change in temperature to the initial temperature to find the temperature of R-134a at the exit of the compressor.
