Liquid acetic acid is being cooled in a heat exchanger from 105°C to 40°C by water flowing through a bundle of 50 tubes. The water enters the tubes at 20°C

with a total flow rate of 8.75 kg s1 and leaves at 45°C. Using the data and appropriate equations from TABLE Q4, you are required to calculate the following: а)The acetic acid volumetric flow rate. (b)The log mean temperature difference if the fluids are in counter-current flow. (c)The film heat transfer coefficient inside the tubes if they have 20 mm inside diameter. (d)The length of the tubes if the overall heat transfer coefficient isW 2K1, assuming the tubes are thin-walled.
