Calculate the exergy of an oxygen-rich stream with 30 percent O2 and 70 percent N2. Consider two cases: the gas stream is at 25 ◦C and at 100 ◦C. The specific heat at 100 ◦C is 1.009 J/(g K). Heat is...

Calculate the exergy of an oxygen-rich stream with 30 percent O2 and 70 percent N2. Consider two cases: the gas stream is at 25 ◦C and at 100 ◦C. The specific heat at 100 ◦C is 1.009 J/(g K).

Heat is available from a large source at a temperature of 150 ◦C. Determine the maximum work that can be done if 100 J of this heat is transferred to a large sink at 25 ◦C.
