1. A heat engine receives 1 kW heat transfer at 1000 K and gives out 400 Was work, with the rest as heat transfer to the ambient at 25?C. What are the fluxes of exergy in and out?

2. In a refrigerator, 1 kW is removed from the -10?C cold space and 1.3 kW is moved into the 30?C warm space. Find the exergy fluxes, including the direction associated with the two heat transfers.
