Question

Problem 2 - Entropy generation in a compression process Nitrogen at 120 kPa and 30°C is compressed to 600 kPa and 190°C in an adiabatic compressor.Calculate the minimum work needed

for this process in kJ/kg. Is this a feasible compression process?Justify your answer based on the entropy generated per unit of mass flowing.
