2 atm. The valve is opened and the two quantities of air are allowed to mix until equilibrium is attained.Employing the ideal gas model with Cv = 0.17 Btu/(lb-°R), determine (a) the final temperature in °F. Ans: 593°R (b) the final pressure in atm. Ans: 1.458 atm (c) the entropy production in Btu/°R. Ans: 0.01928 Btu/ °R
