An ideal refrigerator extracts 410 joules of heat from a reservoir at 290 K and rejects heat to a reservoir at 488 K. What is the ideal coefficient of performance and how much work is done in each cycle?
A refrigerator has a coefficient of performance of 1.15, and it extracts 7.95 J of heat from the cold reservoir during each cycle. (a) How much work is done on the gas in each cycle? (b) How much heat is exhausted into the hot reservoir in each cycle? I've seen a similar question, but I still don't understand how to solve. Can I get help please, step by step would be kind.
QUESTION 1 A heat pump extracts heat from a cold temperature reservoir at 263 K at high temperature reservoir, an auditorium, at 298 K. The heat pump requires (a) Draw a schematic diagram of the heat pump a rate of Q, and rejects 8 kW of heat to a an input power of 2.5 kw system and the reservoirs and show all energies and their values and directions on the diagram. ing an energy balance on the system, determine the...
A Carnot engine extracts 910J from a 550K reservoir during each cycle and rejects 500J to a cooler reservoir. It operates at 22 cycles per second. Find the work done during each cycle. Find its efficiency. Find the temperature of the cool reservoir. Find its mechanical power output.
A refrigerator with a coefficient of performance of 1.80 absorbs 3.15×104 J of heat from the low-temperature reservoir during each cycle. How much mechanical work is required to operate the refrigerator for a cycle? How much heat does the refrigerator discard to the high-temperature reservoir during each cycle?

A refrigerator with a coefficient of performance of 1.77 absorbs 3.64x104 J of heat from the low- temperature reservoir during each cycle.
37. A refrigerator uses 40 J of work to extract heat from a heat reservoir at 0.00°C. If the coefficient of performance of the refrigerator is 2.1, then how much heat is extracted from the heat reservoir at 0.00°C? 90 J 84 J 48 J 65 J
A real refrigerator works between two temperature reservoirs, one at 277 Kelvin, and one at 345 Kelvin. In order to maintain a constant heat flow, during one cycle 350 Joules of heat is transferred from the cold reservoir, while the net work in one cycle is 500 Joules. (a) Obtain the coefficient of performance for this refrigerator. (b) Compare the result in (a) with the ideal case. That is, what is the maximum coefficient of performance if this was an...
