Water at 20 psia and 50F enters a mixing chamber at a rate of 300 lbm/min where it is mixed steadily with steam entering at 20 psia and 240F. The mixture leaves the chamber at 20 psia and 130F, and heat is lost to the surrounding air at 70F at a rate of 180 Btu/min. Neglecting the changes in kinetic and potential energies, determine the rate of entropy generation during this process.

Question

Water at 20 psia and 50F enters a mixing chamber
at a rate of 300 lbm/min where it is mixed steadily with
steam entering at 20 psia and 240F. The mixture leaves the
chamber at 20 psia and 130F, and heat is lost to the surrounding
air at 70F at a rate of 180 Btu/min. Neglecting the
changes in kinetic and potential energies, determine the rate
of entropy generation during this process.
