If there are N shell passes in a shell and tube HE, then which one of the following relation is correct foe the pressure drop a shell side?
Consider we have a shell and tube Heat Exchanger, with the inner tube of diameter 30mm (neglect thickness) and shell of diameter 100mm. We have two fluids A & B (both with viscosity 2.5 10-5Pa-s), we desire to have their flow rates as 4 Kg/s(tube) and 5.3 Kg/s(shell) respectively. What is the Friction Factor (F) for this setup for the shell if it has triangular pitch with Pitch = 40mm?
