A power cycle operates between two thermal reservoirs at 1200 K and 400 K, respectively. For each of the three cases below, determine: (i) The net power produced by the cycle, in kW; (ii) The thermal efficiency; and (iii) Use the Clausius inequality and comparisons to the thermal efficiency of a reversible cycle operating between the given temperatures to determine whether the cycle operates in a reversible or irreversible manner, or is impossible. case | QH(kJ/s) | QL(kJ/s) A | 600 | 400 B | 600 | 0 C | 600 | 200
The system shown is at steady state, steady flow. At inlet 1, the rates of kinetic energy, potential energy and enthalpy entering the system are: KE1 = 0.10 kW, PE1 %3D 0.22 kW, and H1 = 27.0 kW. At inlet 2, the rates are: KE2 = 0.23 kW, PE2 = 0.18 kW, and H2 = 18.0 kVW. At exit 3, the rates are: KE3 = 0.52 kW, PE3 = 0.28 kW, and H3 = 7.0 kW. If the system gives up 5.0 kW of heat to the surroundings, what is the rate of work transfer of the system? Express the answer in kw. %3D KE3 PE3 1 KE. РЕ H. KE2 PE2 На Control volume boundary
Air in a closed piston-cylinder arrangement is expanded from the initial pressure of 8.6 bar and initial volume of 0.021 m to the final state of p2 = 2.8 bar. A polytropic relation of pV3 = constant was followed between pressure and volume for the process. The specific internal energy at the initial and final states are 155.6 and 100.6 kJ/kg, respectively. The mass of the air is 0.22 kg. Neglecting the effect of kinetic and potential energy, determine the heat transfer, in kJ. Answer:
The Kelvin-Planck and Clausius statements of thermodynamics are equivalent. In order to prove the equivalence, a heat-engine-refrigerator combined system is used as shown below. The system satisfies the following conditions, where QH and QL are known values. 1) Heat recieved by the heat engine from the source: QH,HE=QH 2) Heat QH is completely converted into net work output from the heat engine: QH=Wnet 3) Heat recieved by the regrigerator from the sink: QL,R=QL What is the thermal efficiency of the heat engine?__________ A. Wnet/QH=QH/QH=100% B. QL/QH C. QH/QL D. (QH-QL)/QH

A heat pump is used to maintain the interior of a building at 21 °C. At steady state, the heat pump receives energy by heat transfer from well water at 9°C and discharges energy by heat transfer to the building at a rate of 120000 kJ/h. Over a period of 14 days, an electric meter records that 1490 kW-h of electricity is provided to the heat pump. 1. Draw a schematic diagram(s)

The following processes occurs in a reversible thermodynamic cycle: 1-2: Reversible polytropic compression at pressure 0.6 bar at volume 0.07 m3 to a pressure 10.2 bar and specific volume 0.4 m3/kg. The index of compression may be taken as n. 2-3: Reversibly expansion with expansion index of 2 to pressure 3 bar. 3-1: Reversible cooling at constant volume to the initial state. Calculate the value of n in the process to 3 decimal places.
A reversible power cycle whose thermal efficiency is 50% operates between a reservoir at 1800 K and a reservoir at a lower temperature T. Determine T, in K.
