At steady state, 1.8 lb/s of hot gaseous products of combustion cool from p1 = 18.0 lbf/in2, T1 = 2400°F to p2 = 16.0 lbf/in2, T2 = 260°F as they flow through a pipe. Heat transfer from the gas occurs at a boundary temperature of Tb = 230°F. Use the ideal gas model with Cp = 0.25 Btu/lb.°R and an average molecular weight, M = 27.5 lb/lbmol. Let To = 60°F and ignore the effects of motion and gravity.

Determine the exergy transfer accompanying heat transfer from the gas, in Btu/s.

Propane is compressed from an initial state with a pressure of 100 lbf/in2 and a quality of 0.40 to a final saturated liquid state with a temperature is 50°F. Is it possible for this process to occur adiabatically? Justify your answer. Air is contained in a rigid, well-insulated container of volume 3 m3. The air undergoes a process from an initial state with a pressure of 200 kPa and temperature of 300 K. During the process, the air receives 720...
