Two insulated tanks are connected by a valve. One tank initially contains 1.2 ib of air at 240 F, 30 Psia, and the other contains 1.5 ib of air at 60 F, 14.7 psia. 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= 0.18 Btu/lb *R Determine
A) The final temperature, in F
B) the final pressure, in Psia.
C) the amount of entropy produced, in Btu/R
