Question 2 A 1-1 shell & tube exchange is with Sulfuric Acid flowing at 115 gpm, at 80.33 F (Cp=.02 Btu/lbm-F) (SG=1.8), to cool 70 gpm of water from 175 F to 100 F in a counter-current mode. A) Assign shell side fluid. Explain your decision. B) What is the total hot side heat duty? C) Calculate LMTD D) What is the value of Ft and what does it mean? E) Assume a "typical heat transfer coefficient" conservatively, estimate the exchanger area in Ft²?
