Unit 07 1Q) Give a comparison of parallel flow and counter flow heat exchangers. Why are counter flow heat exchangers mosly used? 2Q) Determine the overall heat transfer coefficient based on the outer area of a 3.81cm OD and 3.175cm ID brass tube (k=103.6w/mk) if the heat transfer coefficient for flow inside and outside the tube are 2270 and 2840w/m2k respectively and the unit fouling resistances at inside and outside are Rfi=Rfo=0.0088m2k/w 3Q) Derive an expression for logarithmic mean temp difference
