The ratio of heat transfer to work transfer in the process of an air compressor reciprocating type is 1/4. If the compression follows pvn = constant, what is the value of n? Derive the equation that you use.
In such a compression process the work required is 200 kJ/kg and the specific heat at constant volume is 0.75 kJ/kg K. What rise of temperature is expected at the end of compression process?
