An ideal gas initially at 600 k and 10 bar undergoes a four-step mechanically reversible cycle in a closed system .in step 12, pressure decreases isothermally to 3 bar, in step 23, pressure decreases at constant volume to 2 bar, in step 34, volume decreases at constant pressure; and in step 41 ,the gas returns adiabatically to the initial state. take cp=(7/2)r and cv=(5/2)r
(a) sketch the cycle in pv diagram.
(b) determine (where unknown) both t and p or state 1, 2, 3, and 4.
(c) calculate w, q, δu, and δh for each step of the cycle.
