An ideal gas whose adiabatic exponent is equal to (gamma) undergoes a cycle consisting of two isochoric and two isobaric lines. The absolute temperature of the gas both in the isochoric heating and the isobaric expansion. 1. Sketch the cycle indicating the isobars and the isochores 2. Write down the relationship between the temperatures at the relevant points on the sketch.
(a) Sketch the cycle on a p V diagram. (b) Calculate the net work for the cycle, in kJ. (c) Calculate the heat transfer for process 2 3, in kJ. (d) Calculate the heat transfer for process 3 1, in kJ. (e) Is this a power cycle or a refrigeration cy..
