< Q5: Determine the COP of a refrigerator which removes heat from the food compartment at a rate of 6000000 J/h for each 1200 W of power it consumes. A: 1.35 OB: 1.36 C: 1.37 D 1.38
1.2 A reversible heat pump is used to maintain a temperature of 0°C in a refrigerator when it rejects the heat to the surrounding at 25°C. (i) If the heat removal rate from the refrigerator is 1440 kJ/min, determine the COP of the machine and work input required. (ii) If the required input to run the pump is developed by a reversible engine which received heat at 380°C and rejects heat to atmosphere, then determine the overall COP of the system.
2. An internally reversible heat engine operates between intake and heat release temperatures between 627 and 27 °C. Part of the work generated by the heat engine is used to move an internally reversible refrigeration machine that works between temperatures of 27 and -23 °C. The heat supplied to the engine is 2100 kJ and the net work output (the work of the engine minus that consumed by the refrigerating machine) is 500 kJ. Determine a) The heat transferred to the refrigerating machine at -23°c b) The net heat transferred at 27 °C
Hi I need help with a thermo review question- thank you! A refrigerator transfers 6 kW of heat from the cold space at 277 K and transfers 10kW of heat to the surroundings at 300 K. a) Determine the Rate of Work input required (kW). b) Determine the Refrigerator Coefficient of Performance c) Determine the Coefficient of Performance if it’s a Carnot Refrigerator
2. A heat pump is like a refrigerator in that it uses work to take heat from a cold source (Tc, the inside of a house) and dumps it into a hot source (Th, usually the outdoor environment). a) Use the second law to find the magnitude of the work |w| needed to extract |qc] from the cold source and dump into the hot source. b) Assume all processes are reversible and the second law to explain why |w| > 0 if lgc] > 0 in part a).
b) A heat engine operates between two reservoirs at 800° C and 20° C. One-half of the work output of the engine is used to drive a Carnot heat pump that removes heat from the cold surroundings at 2° C and transfers heat to a house maintained at 22° C. If the house is losing heat at a rate of 62,000 kJ/h, determine the minimum rate of heat supply to the heat engine required to keep the house at 22° C.
Suppose you have two kettles – a plug-in electric kettle and a stovetop kettle. The electric kettle uses electricity from a natural gas fired powerplant, while you boil water in your stovetop kettle on a natural gas burner. a) Based on the following information, which of these kettles demonstrates a higher energy efficiency (i.e., which is more efficient at using energy from fuel to heat water)? Please calculate the efficiencies of each kettle and express answers as percentages. -The natural gas power plant converts chemical energy of the natural gas to electricalenergy with 58% efficiency. -High-voltage power lines from the power plant to your house convey electricity with92% efficiency. -The electric kettle converts electrical energy to thermal energy in the water with 85%efficiency (the other 15% heats up the kettle itself). -The stove burner converts chemical energy of natural gas to thermal energy with 98%efficiency (the other 2% is light). -The stovetop kettle transfers 35% of…
Question 5 A cyclic system exchanges heat with 3 reservoirs. The system receives 990 J from a reservoir at 1,236 Kand 542 J from a reservoir at 766 K. It rejects an unknown quantity of heat to a reservoir at 256 K. What is the maximum possible efficiency of the system? Give your answer as a percentage to 1 decimal place (e.g. 12.3% would be input as 12.3).

b) Steam generators are a type of heat exchanges that are used in power plants to generate steam at desired pressure and temperature (Fig. Q1.b). In a steam generator, saturated liquid water at 30°C enters a 60-mm diameter tube at the volume flow rate of 12 L/s. After exchanging heat with hot gas, the water changes to steam and leaves the generator at a pressure of 9 MPa and a temperature of 400°C. During this process, the diameter of the water/steam tube does not change. Steam out Gas out Hot gas in Liquid water in Fig 2. Schematic of the steam generator in Q1.b. (i) Calculate the steam mass flow rate (ii) What is the inlet velocity of the steam? (iii) What is the exit velocity of the steam? (iv) Calculate the rate of heat transfer (in MW) required to change the phase of liquid water to steam.
