Question
For Problem 7-86, the heat transfer may be calculated for reversible isothermal ideal gas to be mRTln(V2/V1) and the work may be calculated from quasi-equilibrium polytropic relationships to be mRTln((V2/V1). The First Law also says that Q12=W12 What does all this imply for how reversibility relates to isothermal quasi-equilibrium?
of the final pressure for the two cases as the final pressure varies from 1 to 12 kPa. An insulated rigid tank contains 4 kg of argon gas at 45 kPa and 3 degree C. A valve is now opened, and argon is allowed to escape until the pressure inside drops to 2 kPa. Assuming the argon remaining inside the tank has undergone a reversible, adiabatic process, determine the final mass in the tank.Explanation / Answer
