Question

An inventor claims to have created a machine that isothermally compresses 1 lbmol/hr of an
ideal gas at 1000 oR releasing 3000 Btu which is transferred to another 1 lbmol/hr of ideal
gas that expands isothermally from 2.72 atm to 1 atm. Is such a device possible or does this
process violate the second law? Assume the process is reversible. R = 1.987 Btu/lbmol oR.

m = 1 lbmol/hr m = 1 lbmol/hr T₁ = 1000 °R P3 = 2.72 atm W W Q T₂ = 1000 °R = 3000 Btu/hr P₁ = 1 atm m = 1 lbmol/hr m = 1 lbmol/hr
