One mole of ideal gas initially at 750 K and 11.84 atm undergoes a four- step mechanically reversible cycle in a closed system. First pressure decreases isothermally to 4.93 atm; then pressure decreases at constant volume and change in Enthalpy = - 8730 J; then volume decreases at %3D constant pressure with change in internal energy -5334 J; and finally, the gas returns adiabatically to its initial state. Sketch the cycle and Determine (where unknown) T, V and P and Calculate the four faction for The irreversible cycle with an efficiency of 85%.
