Question

Q1. In a reversible cycle 1.5 kg of air is heated at constant volume, from a pressure and temperature of 1 bar and 25℃ respectively to a pressure of 7 bar. It is then isothermally expanded to the original pressure and finally it is cooled at constant pressure to the initial volume.

(a) Sketch The cycle on Pressure-Volume and Temperature-specific entropy diagrams.(4)

(b) Calculate EACH of the following:

(I) The network transfer; (4)

(ii) The Thermal efficiency for the cycle; (3)

(iii)The efficiency of a Carnot cycle operating between the same temperature limits. (3)

(c) Sketch the Carnot cycle on a Temperature-specific entropy diagram. (2)

Note: for air  and
