Question
Mean Temperature Difference in an Exchanger. A l–2 exchanger with one shell pass and two tube passes is used to heat a cold fluid from 37.8°C to 121.1°C by using a hot fluid entering at 315.6°C and leaving at 148.9°C. Calculate the A Tim and the mean temperature difference AT, in K. Ans. ATim = 148.9 K;AT„ = 131.8 K (Hint : read the section in Geankoplis textbook on how to apply a correction factor on log-mean temperature difference for a one-shell pass and two-tube passes exchanger .)
