CHEMICAL ENG.THERMODYNAMIC FO A gas at pressure P, and temperature Ty is steadily exhausted to the atmosphere at pressure P2 through a pressure-reducing valve. Find an expression relating the downstream gas temperature T, to P1, P2, and T). Since the gas flows through the valve rapidly, one can assume that there is no heat transfer to the gas. Also, the potential and kinetic energy terms can be neglected. Topi -T2 = ?, P2 La densitat
