A fluid at 0.7 bar occupying 0.09 m ³ is compressed reversibly to a pressure of 3.5 bar according to the law Pv ⁿ =constant the fluid is then heated reversibly at constant volume until the pressure is 4 bar the specific volume is then 0.5 m ³ /kg. A reversible expansion according to the law pv ² =constant restore the fluid to its initial state.

a. Calculate the mass of the fluid present

b. Calculate the value of n in the first process
