The temperature inside a Carnot refrigerator is maintained at 5ºC by rejecting heat to the surroundings at an ambient temperature of 27ºC. The inside temperature now decreases to -13ºC with the ambient temperature remaining constant at 27ºC. Determine the percent increase in work input for the same quantity of heat, QL, removed.

It is desired to reverse the cycle and use it as a refrigerator. In this case the process would begin with PV1.36 = constant process from an initial state of 293 K and a pressure of 10 Bars. The gas is allowed to expand to a volume 3.5 times the volume of state 1. It then follows a constant volume process in which the temperature is raised to 323 K. A constant temperature is followed back to volume 1.   A...

5 kg of air in a piston cylinder assembly undergoes a Carnot power cycle. Heat is received at temperature?1=727°C and rejected at ?3=27°C.During the heat input process, the pressure changes from ?1=1200kPa to ?2=900kPa, respectively. Assume the air behaves as an ideal gas with constant specific heats. Determine: a.pressures [kPa] at beginning and end of the isothermal heat rejection process (?3,?4) b.heat transfer from high temperature source [kJ] c.thermal efficiency d.net work output for cycle [kJ]

A simple (non-cyclic) heat engine. Consider a cylinder containing an ideal gas under a piston, as shown in Figure below. After a weight m1 is removed from the piston, the gas expands, lifts the remaining weight m2, and the piston eventually settles at a new position h2. A. Assuming that the above process is carried out in a room whose temperature is maintained constant so that the initial and the final temperature of the gas is exactly the same, what...
