: 6 A Gas Mixture Required In An Industrial Process Is Prepared By First Allowing Carbon Monoxide Co At 80 F 18 Lbf In 1 (18.48 KiB) Viewed 29 times

6. A gas mixture required in an industrial process is preparedby first allowing carbon monoxide (CO) at 80°F, 18lbf/in2 to enter an insulated mixing chamber operatingat steady state and mix with argon (Ar) entering at 380°F, 18lbf/in2 . The mixture exits the chamber at 140°F, 16lbf/in2 and is then allowed to expand in a throttlingprocess 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 andthe valve, each in Btu per lb of mixture, forT0=40°F.
Kinetic and potential energy effects can be ignored.
