A mass of 27 lbm of helium undergoes a process from an initial state of 50 ft3/ Ibm and 60°F to a final state of 20 ft3/lbm and 240°F. Determine the entropy change of helium during this process assuming the process is irreversible. The gas constant of helium is R= 0.4961 Btu/lbm-R. The constant volume specific heat of helium at room temperature is cy= 0.753 Btu/lbm-R.
