Flow Characterisitc (Entrance Effects) Why was there some disagreement between the actual Pitot tube velocity profile and the power law velocity profile?
Consider the shell and tube heat exchanger where liquid A of density pa is flowing through the inner tube and is being heated from temperature Tat to Taz by liquid B of density pe flowing counter-currently around the tube The temperature of liquid B decreases from Ten to Tea. In many practical situations the tubular heat exchanger is modelled using simple ordinary differential equations. This is possible if we think about the heat exchanger within the unit as being an exchanger between two perfect mixed tanks. Each one of them contains a liquid. i Investigate the nature of a system a heat exchanger under ideal conditions ii.
