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

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Because of the selective permeability of the membrane only water and other very small particles (iodine) can be diffused through simple diffusion. The solution out of the dialysis tubing had a higher distelled iodine concentration of solutes (iodine + H2O) than did the starch solution. So iodine move into the cell and react with starch molecules to formed starchiodine‚ the blue compound
