Ideal gas at pressure of Ibar, volume 0.5m ", and temperature 15 ° C. The gas pressed isothermally to a pressure of 10bar, and then it's expanded adiabatically to its original volume. If you know that y = 1,41 and C = 1,001kJ / kg K. Draw the processes on P - V & T - S diagrams, and determine: I) Net heat transferred in kJ. II) The total change in internal energy
A) A heat engine cycle operating between two reservoirs receives energy Qudd from a hot reservoir at Th = 1200 ° K and rejects energy Qre to a cold reservoir at T. = 25 ° C. For each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, or is impossible: (1) Qrej = 10MJ, Wet = 80MJ. (II) Qrej = 1.2M), Qasd = 2000kJ. (III) Osw = 200MJ, Wet = 0.16). (IV) Efficiency of 75.2% B) Ideal gas at pressure of Ibar, volume 0.5m ", and temperature 15 ° C.
