Air enters a compressor steadily at the ambient conditions of 100kPa and 20 degrees celcius and leaves at 900 kPa. Heat is lost from the compressor in the amount of 150kJ/kg and the air experiences an entropy decrease of 0.50kJ/kg*K. Using constant specific heats, determine (a) air exit temperature, (b) work input to the compressor, and (c) entropy generation during the process.

Asked Apr 3, 2019

Air enters a compressor steadily at the ambient conditions of 100kPa and 20 degrees celcius and leaves at 900 kPa. Heat is lost from the compressor in the amount of 150kJ/kg and the air experiences an entropy decrease of 0.50kJ/kg*K. Using constant specific heats, determine (a) air exit temperature, (b) work input to the compressor, and (c) entropy generation during the process.

Step 2

On substituting the values,
We have the value as below: -

Thus, the value of work input to the compressor is 192. 6727 kJ/kg.
