Helium gas is throttled steadily from 500 kPa and70°C. Heat is lost from the helium in the amount of 2.5 kJ/kg to the surroundings at 25°C and 100 kPa. If the entropy of the helium increases by 0.25 kJ/kg · K in the valve, determine (a) the exit pressure and temperature and (b) the entropy generation during this process.
