Answer to Question #344153 in Mechanical Engineering for nessah

Question

A fluid at 0.7bar occupying 0.09m^3 is compressed reversibly to the pressure of 3.5bar according to the law pv^n=C. The fluid is heated reversibly at constant volume until the pressure is 4bar, the specific volume is then o.5m^3/kg. A reversible expansion according to the law pv^2=C restores the fluid to its initial state. Sketch the graph and calculate the mass of the fluid present, the value of the n in the first process, and the network of the cycle.
