Asteady state device converts 2 mol/s of xenon gas from 400 k and 20 mpa to 300 k and 15 mpa. in the process, no work is done but a certain rate of heat is rejected to a cold reservoir in the surroundings that is maintained at 273 k. determine the heat flow expected from this process and whether the device is feasible. assume xenon follows the principle of corresponding states (plots can be downloaded from learn) and its cp 21 j/mol k.
