THE FLOW RATE MEASUREMENT EXPERIMENT

BY NAKIBUL HUSSAIN NUHASH

Abstract The purpose of the experiment is to analyse the difference between the mass flow rates when measured with a Venturi and with a Pitot probe across a cylindrical pipe. We have compared the mass flow rate in the Venturi and mass flow rate in the pipe with Pitot tube. There is a considerable difference found between the calculated values of mass flow rates, and in the report we are going to discuss the reason for this difference and make a conclusion.

Introduction In this lab experiment we are going to investigate mass flow rate using Venturi meter, and compare this with the mass flow rate determined from the velocity profile measured through a uniform crosssectional pipe with a Pitot probe. The inclined manometers and Electronic Pressure Transducer (EPT) are connected to the Venturi meter, Pitot tube and pipe at certain positions to determine the change in pressure of fluid (air) while flowing. In the experiment we are assuming that air is an ideal fluid i.e. incompressible and inviscid, and the flow is a steady, laminar flow (or streamline flow). Temperature (T) and atmospheric pressure (P) can be recorded using barometer. So density () of air can be found using the equation of state for an ideal gas. [John D. Anderson, JR. (2005).] This can be expressed as: = Equation (1)

Background Theory We know the Bernoulli’s equation: P1 + V12 + Z1 = P2 + V22 + Z2 Equation (2)

“Bernoulli’s equation relates the pressure (P1 and...
