Question:

Aniline is to be cooled from 200 to 150°F in a double-pipe heat exchanger having a total outside area of 70 ft2. For cooling, a stream of toluene amounting to 8,600 lb/h at a temperature of 100°F is available. The exchanger consists of 11/4-in. Schedule 40 pipe in 2-in. Schedule 40 pipe. The aniline flow rate is 10.000 lb/h. 

(a) If flow is countercurrent, what are the toluene outlet temperature, the LMTD, and the overall heat transfer coefficient? 

(b) What are they if flow is parallel?
