In the shell of a shell-and-tube heat exchanger with two shell passes and eight tube passes, 12.6

Question:

In the shell of a shell-and-tube heat exchanger with two shell passes and eight tube passes, 12.6 kg/s of water is heated from 80°C to 150°C. Hot exhaust gases having roughly the same physical properties as air enter the tubes at 340°C and leave at 180°C. The total surface area, based on the outer tube surface, is 930 m2. Determine 

(a) The log mean temperature difference if the heat exchanger is the simple counter flow type

(b) The correction factor F for the actual arrangement

(c) The effectiveness of the heat exchanger

(d) The average overall heat transfer coefficient
