An inventor claims to have devised a refrigeration cycle operating between hot and cold reservoirs at 308 K and 278 K, respectively, that removes an amount of energy QC by heat transfer from the cold reservoir that is a multiple of the net work input—that is, QC = NWcycle, where all quantities are positive. Determine the maximum theoretical value of the number N for any such cycle.
The steam from a boiler
enters a steam turbine and
work is done by the steam
turbine. After work done, the
steam is condensed by
condenser. The condensate
(water) is again sent to the
boiler to generate the steam.
Choose the correct type of
thermodynamic system
involve in this operation.
O a. Open system
O b. Adiabatic system
O C. Isolated system
o d. Closed system
The first step of a thermodynamic cycle is an isobaric process with increasing volume. The second is an isochoric process, with decreasing pressure. The last step may be either an isothermal or adiabatic process, ending at the starting point of the isobaric process. Sketch a graph of these two possibilities, and comment on which will have greater net work per cycle.

- Describe an imaginary process that satisfies the first law but violates the second law of thermodynamicsarrow_forwardb) Refrigerators are systems that are used to remove heat from a cooled space then reject heat to a space of higher temperature. Consider a refrigerator operating at normal conditions, removing heat from a cool space at a rate of 150 kJ/min to ensure the refrigerated space is kept at -5 °C. If the surrounding air is at 27 °C and assuming that the refrigerator is operating as a Carnot cycle, determine: 1) The rate of heat being rejected to the surrounding in kJ/min The coefficient of performance of this refrigeration process 11) 111) The minimum required power on this process (give your answer in kW)arrow_forwardAir within a piston-cylinder assembly executes a Carnot heat pump cycle, as shown in the figure below. For the cycle, TH = 600 K and TC = 300 K. The energy rejected by heat transfer at 600 K has a magnitude of 1000 kJ per kg of air. The pressure at the start of the isothermal expansion is 325 kPa. Assuming the ideal gas model for the air, determine: (a) the magnitude of the net work input, in kJ per kg of air, and (b) the pressure at the end of the isothermal expansion, in kPa.arrow_forward
