Question: Repeat Problem 12.50 for an isentropic compressor efficiency of 82%. Problem 12.50 Natural gas as a mixture of 75% methane and 25% ethane by mass

Repeat Problem 12.50 for an isentropic compressor efficiency of 82%.
Problem 12.50
Natural gas as a mixture of 75% methane and 25% ethane by mass is flowing to a compressor at 17°C, 100 kPa. The reversible adiabatic compressor brings the flow to 250 kPa. Find the exit temperature and the needed work per kg flow.
