Solve what is asked on the problem below.
H6. An air conditioner in an upper-floor apartment unit is turned on during a hot summer afternoon. If heat can be removed from the interior at a rate of 1.5 kW, estimate the time required to cool the air inside the apartment to its final temperature. Your estimate should create any needed input data and should incorporate factors like the size of the apartment and the behavior of air.
A new parabolic dish solar concentrator is being developed to supply electricity to a small remote community. The system operates with a Stirling engine connected to two heat reservoirs HR₁ and HR₂ as shown in Fig. Concentrated solar radiation Q˙ₛᵤₙ=200kW maintains HR₁ at constant temperature Tₕᵣ,₁=700℃, and a high performance heat sink device maintains HR₂ at temperature Tₕᵣ,₂=25℃. After some time of operation, an engineer working on the project realizes that the engine power output is performing below design specifications and only provides a power output of 120kW. After inspecting the system, they discover a contact resistance that causes the thermal communication between the two heat reservoirs and the engine to be imperfect in the sense that a finite temperature difference is required to establish heat transfer between each of the heat reservoirs and the engine. Assuming the engine itself is internally reversible, estimate the rate of entropy generation in the engine’s…

7.1 (20%) A Carnot heat engine transfers 13.5 kW of waste heat output to low-temperature the energy reservoir which is at 15°C. The net power output from the heat generator is 16.5 kW. The power output (Wut, net) from the heat generator is transferred without loss to a Carnot heat pump. The heat pump transfers energy from the heat generator's low-temperature energy reservoir to an energy reservoir with a constant temperature of 50°C. termisk energireservoar Онукм Carnot- varmekraft- maskin LVKM шлепо termisk termisk energireservoar TRYP QH.NP Carnot- varmepumpe QLVP energireservoar T₁ a) What power does the Carnot thermal power engine receive from the heat source in kW and what temperature is it the heat source in "C? b) What power factor does this Carnot heat pump have and what heat output does it deliver to the area with 50°C temperature?
