... process, some of the heat can be transformed into mechanical work. Equation (12-9) expresses the fundamental upper limit to the efficiency. No engine operating between the same two temperatures can be more efficient than a Carnot engine. Real engines always have efficiency lower than this because of ...

... Both are recognized at the boundaries of a system as they cross the boundaries. That is, both heat and work are boundary phenomena. Systems possess energy, but not heat or work. Both are associated with a process, not a state. Unlike properties, heat or work has no meaning at a state. Both are path ...

... 7. A system contains 0.2 m3 of a gas at a pressure of 4 bar and 150°C. It is expanded adiabatically till the pressure falls to 1 bar. The gas is then heated at a constant pressure till its enthalpy increases by 100 kJ. Determine the total work done. Take Cp =1 kJ/kgK and Cv = 0.714 kJ/kgK. Or 8. 12 ...
