Webb) The contents of the freezer in a home refrigerator are maintained at 253 K(-20 0 C). The kitchen temperature is 293 K (-20 0 C). If heat leaks amount to 125000 W per day, and if electricity costs $0/kWh, estimate the yearly cost of running the refrigerator. Assume a coefficient of performance equal to 60% of the Carnot value. 6 Marks 5 Marks. 8. WebT-s diagram of two Carnot vapor cycles. The Carnot cycle is the most efficient cycle operating between two specified temperature limits but it is not a suitable model for … WebThe reversed Carnot cycle is the reversible (ideal) cycle that has the thermodynamically highest possible COP and is composed of two isothermal and two isentropic (adiabatic) processes. Figure 2 shows the Carnot refrigeration (a–b–c–d–a) and the Carnot heat pump (1–2–3–4–1) cycles traced in the temperature–entropy plot. how to roast your siblings
