numericals of thermodynamics workdone calculation according to linear law
The question: 1 kg of a fluid expands reversibly according to a linear law from 4.2 bar to 1.4 bar;the initial and final volumes are 0.004m^3 and 0.2m^3. The fluid is then cooled reversibly at constant pressure,and finally compressed reversibly according to a law pv=constant back to the initial conditions of 4.2 bar and 0.004m^3. Calculate the workdone in each process and the net work of the cycle. Sketch the cycle on a p-v diagram.
please help me to solve this please |
