A fluid at 0.7 bar occupying 0.09 m^3 is compressed reversibly to a pressure of 3.5 bar according to a law pvⁿ = constant. The fluid is then heated reversibly at constant volume until the pressure is 4 bar: the specific volume is then 0.5 m³/kg. A reversible expansion according to a law pv² = constant restores the fluid to its initial state. Sketch the cycle on a p-v diagram and calculate:

(i) the mass of fluid present;

(ii) the value of n in the first process;

(iii) the net work of the cycle.
