Question

Problem

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^oC. What are the fluxes of exergy in and out?

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

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
