Experimental prediction of pressure drop and friction coefficient of Gas –solid fluid flow in a circular tube

Abstract

Abstract:-This study explains the relationship between friction coefficient and pressure change at a range of Reynolds (21056 - 32033) and (0 -1.4) solid loading ratio of two phase flow (Gas-solid) inside a circular copper pipe of (63mm) inside diameter and (2m) length by using laboratory apparatus and solving the equations mathematically . An experimentally relationships of friction coefficient and pressure change with Reynolds number and flow velocity one obtained also the relationship between the solid loading ratio with friction coefficient and pressure change has been done for a limit range of Reynolds number . It is noticed that the increasing in friction coefficient and pressure change for two phase flow was occurred when solid loading ratio increasing. Also the relationship between pressure change and Reynolds number was direct proportion while the relationship between friction coefficient and Reynolds number were inversely related
