Determine
(a) the mass and molar analyses of the mixture.
(b) the temperature of the mixture at the exit of the valve, in°F.
(c) the rates of exergy destruction for the mixing chamber andthe valve, each in Btu per lb of mixture, forT0=40°F.
Kinetic and potential energy effects can be ignored.
6. A gas mixture required in an industrial process is prepared by first allowing carbon monoxide (CO) at 80°F, 18 lbf/in² to enter an insulated mixing chamber operating at steady state and mix with argon (Ar) entering at 380°F, 18 lbf/in². The mixture exits the chamber at 140°F, 16 lbf/in² and is then allowed to expand in a throttling process through a valve to 14.7 lbf/in² Determine (a) the mass and molar analyses of the mixture. (b) the temperature of the mixture at the exit of the valve, in °F. (c) the rates of exergy destruction for the mixing chamber and the valve, each in Btu per lb of mixture, for To-40°F. Kinetic and potential energy effects can be ignored.
