Unformatted text preview: (a) Assuming constant specic heats at room temperature, calculate the exit temperature of the mixed ow. (b) Again assuming constant specic heats, calculate the rate of entropy generation for the mixing process. 3. An inventor claims to have a device which will take 0.1 m 3 /s of air at 300 K, 1 atm, and produce separate streams, each at 300 K and 1 atm, of pure O 2 and N 2 . The device exchanges heat only with the environment and consumes 5 kW of power. Assuming air is 0.21 O 2 , 0.79 N 2 on a mole basis, and taking the environment temperature to be 300 K, determine the validity of this claim. 1...
