Find the entropy production and determine if the cycle operates irreverisbly, reverisbly, or impossibly. A refrigeration cycle operates between the freezer compartment at 268K and the ambient air at 295K. The rate of heat transfer from the freezer compartment is 8000 kJ/h and the power input for the cycle is 3200 kJ/h. Determine the entropy production for this cycle in kJ/K·h (do not convert h to s). Enter the answer without units, but with a minus sign if applicable. This cycle operates irreversibly reversibly impossibly.

Consider a simple ideal Brayton cycle with air as the working fluid. The pressure ratio of the cycle is 7.2, and the minimum and maximum temperatures are 300 K and 1350 K, respectively. Now the pressure ratio is doubled without changing the minimum and the maximum temperatures in the cycle. Assuming constant specific heats for air at room temperature; show the initial process and process change in a T-s diagram; calculate the change in the net work output per unit mass; and determine the change in thermal efficiency of the cycle.
