A mass of 35lbm of helium undergoes a process from an initial state of 50ft3/lbm and 60F to a final state of 20ft3/lbm and 240F. Determine the entropy change of helium during this process assuming the process is irreversible. The gas constant of helium is R=0.4961Btu/lbmR. The constant volume specific heat of helium at room temperature is cV=0.753Btu/lbmR. The entropy change of helium during this process is Btu/R
