You have three devices: a Carnot heat engine, a Carnot heat pump and a Carnot refrigerator. Use a cold reservoir temperature of -18C. Plot the heat engine Carnot efficiency, the COPrefrig, and the COPhp as a function of the hot reservoir temperature from 27C to 177C. Use temperature increments of 5K in your plot. Make sure and reference a previous slide 'how to make a plot' that gives you the key elements of making a graph (in your choice of software). Describe what you see. Also describe the illustrated relationship between COPhp and COPref.

3.5 A novel heat engine is being considered for producing work from the thermal energy contained in the wastewater discharge from a large food-processing plant. On an average day, 35 ° C wastewater leaves the plant and is discharged into the ocean at 1,000 gallons per minute. If the average annual ocean temperature is 10 ° C at that location, what is the maximum power that could be produced by this heat engine? What would be the thermal cycle efficiency of your maximum power engine? You can assume that the heat capacity of water at constant pressure is constant at 4,200 J/kg K.
