(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.arrow_forward

- 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).arrow_forwardThermodynamics- hand write plsarrow_forwardQuestion 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).arrow_forward
- 3.5 A novel heat engine is being considered for producing work from the thermal energy contained in the wastewater discharge from a large food-processing plant. On an average day, 35 ° C wastewater leaves the plant and is discharged into the ocean at 1,000 gallons per minute. If the average annual ocean temperature is 10 ° C at that location, what is the maximum power that could be produced by this heat engine? What would be the thermal cycle efficiency of your maximum power engine? You can assume that the heat capacity of water at constant pressure is constant at 4,200 J/kg K.arrow_forwardPlease show steps I keep coming up with -0.0044arrow_forwardb) 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.arrow_forward
