Fluid Flow In a Duct of Varying Cross-Section.

... FLUID FLOW IN A DUCT OF VARYING CROSS-SECTION By: BILAL GHALY B.ENG AERONAUTICAL ENGINEERING GROUP B1 Introduction The purpose of this experiment was to demonstrate the relation between pressure and fluid velocity in a duct of varying cross-sectional area. This experiment is carried out on the basis of conservation of mass and energy. Both the Bernoulli's equation and the Continuity equation are essential analytical tools used for the analysis of problems in the subject of Mechanics of Fluids, in this case flow of fluid in the venturi. The constant flow rate in the varying cross-section duct suggests that the fluid velocity and pressure should compensate this varying cross-section accordingly. As the varying cross-section becomes convergent the velocity and pressure of the fluid is at its highest value. Thus signifying that the at the divergent or diffuser end the velocity and pressure of the fluid should progressively go back to its original values. Theory The continuity equation states that
