A fluid at 0.7 bar occupying 0.09m³ is compressed reversibly to a pressure of (a) 3.5 bar according to a law pv" = constant. The fluid is then heated reversibly at constant volume until the pressure is 4 bar: the specific volume is then 0.5m³/kg. A reversible expansion according to a law pv = constant restores the fluid to its initial state. Sketch the cycle on a p-v diagram and calculate: i) the mass of the fluid present; ii) the value of n in the first process; 1. iii) the net work of the cycle.
