ABOUT ME: MECHANICAL TECHNOLOGIST IN PSU @RANCHI, JHARKHAND GATE QUALIFIED WITH 809 SCORE IN 2015 B.TECH. FROM BIT SINDRI, DHANBAD, JHARKHAND 2K11-2K15 A MECHANICAL ENGINEER THAT CAN SING
Hydraulic diameteir = Do-Di 0 For an annular duct, such as the outer channel in a tube-in-tube heat exchanger the hydraulic diameter can be shown algebraically to reduce to Do D Where Dg is the inside diameter of the outside pipe, and D, is the outside diameter of the inside pipe.
Post-lecture question Find the boundary layer thickness at x=100 cm if at x = 16cm it is 1 mm. If Reynolds number is 10000 for the flat plate case. 4.91 (Blasius equation)valid for laminar flow Thus, Rex = = 100 = 2.5 Graphics used in Illustrations by Ravi Singh Choudhary
