An ideal gas that is heated at constant pressure enters the steady-flow heat exchanger at 343.15 K. This was heated by another stream of the same ideal gas which enters at 593.15 K into its final temperature of 463.15 K. Assume that the drop in the temperature of the second stream is the same as the rise in the temperature of the second stream. The flow rates of the two streams are the same, and no heat losses occur during the whole process. Assume that Cp = 7/2R.

Cold working is done at temperatures O A. below the room temperature O B. below the recrystallization temperature O C. below ductile-to-brittle transition temperature O D.below the melting point A Moving to another question will save this response. AL O É

Thank you for you reply I appreciate it. Would you be able to expand on what you did for the integration at the for Part A please?

pls solve this fast . I will give multiple upvote
