A heat engine operates between 800 K and 300 K, but its efficiency is only 80% of the maximum possible. What is the actual efficiency of the engine? 30% 70% 38% 50% 36%
A power cycle operates between a lake’s surface water at a temperature of 300 K and water at a depth whose temperature is 285 K. At steady state the cycle develops a power output of 10 kW, while rejecting energy by heat transfer to the lower temperature water at the rate 14,400 kJ/min. Determine (a) the thermal efficiency of the power cycle and (b) the maximum thermal efficiency for any such power cycle. I have no idea on how to...
can someone help me with question Help A heat engine is operating on a Carnot cycle and has a thermal efficiency of 48.5 percent. The waste heat from this engine is rejected to a nearby lake at 60°F at a rate of 800 Btu/min. Source TH Carnot HE 800 Btu/ min Sink 60°F Determine the power output of the engine. (You must provide an answer before moving to the next part.) The power output of the engine is hp
