During January, at a location in Alaska winds at -10°C can be observed, However, several meters below ground the temperature remains at 11°C. An inventor claims to have devised a power cycle working between these temperatures having a thermal efficiency of 10%. Investigate this claim. What is the maximum thermal efficiency for these conditions.

Problem #2 17.5 pts)Topic. Entropy A typical gasoline engine operates at 200°F while the maximum temperature inside the combustion chamber can be 1100F. On the other hand, the temperature of the combustion chamber of a typical diesel engine can reach up to 2500 F. So let's compare the performances of two Carnot cycles, one operating between ~1100°F and 200°F heat reservoirs and the other between ~2500°F and 200°F, to have a first-order crude estimate of engine performance Step a) Choose...

Q2. A heat pump cycle is operating reversibly between a warm reservoir at 20o C and a cold reservoir at -5o C. A second heat pump cycle is also operating reversibly between a hot reservoir at 30o C and a cold reservoir whose temperature, TC, is unknown. Given that the coefficient of performance of the first heat pump cycle is twice that of the second cycle, determine TC (in o C). Q3. You see a newspaper advertisement from an organization...

For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
