Applying the Exergy Balance: Closed Systems

Figure P7.83 provides steady-state operating data for a mixing chamber in which entering liquid and vapor streams of water mix to form an exiting saturated liquid stream. Heat transfer from the mixing chamber to its surroundings occurs at an average surface temperature of 100^oF. The effects of motion and gravity are negligible. Let T₀ = 70^oF, p₀ = 1 atm. For the mixing chamber, determine, each in Btu/s, (a) the rate of heat transfer and the accompanying rate of exergy transfer and (b) the rate of exergy destruction.
