Unformatted text preview: effect of friction. Plot the cycle in pV coordinates. Determine the missing state variables p 2 and p 4 and the net work input W net (in joules). Example 4: The compound system in the sketch below contains a gas ( C v = 2.5 mR ) on both sides of an internal wall. As heat is transferred across the wall, the piston moves to the right until the gases obtain thermal equilibrium at T 2 . During this process the shaft force F shaft maintains the pressure for system B constant at 3 bar. Also, P A1 = 10 bar, T A1 = 1000 K, V A = 1 liter, and P B1 = 3 bar, T B1 = 300 K, and V B1 = 1 liter. Determine ( i ) the heat capacities at constant volume and at constant pressure for the gas: C v and C p ; ( ii ) the missing thermodynamic state properties: T 2 , P A2 , and V B2 ; ( iii ) the heat transferred from system A to B, Q AB , the pressure work out of system B, W B and the shaft work, W S . Do not neglect the affects of atmospheric pressure, P = 1 bar. F shaft Q AB A B...
