Question

COP of reversed Carnot engine is a function of temperature only *
True
False​

Answer 1

Answer:

True and False 1. COP of a Carnot system depends only on the refrigeration and heat rejection temperatures only. (Answer) 2. As heat transfer from a gas can be done isothermally, Carnot cycle is easy to implement practically. (Answer) 3. For a fixed heat rejection and refrigeration temperature, the COP of a brayton cycle is lower than COP of reverse Carnot cycle. (Answer) 4. Efficiency of dense air systems are low as operating pressures are higher (Answer) 5. DART is the temperature of the air at the exit of the cooling turbine. (Answer) 6. A Simple system is adequate to handle high Mach numbers. (Answer)
