velocity to increase as it passes through a constricted section of a pipe. This is the basis of this report’s investigation. The aim of this investigation is to compare the flow rate obtained from the Venturi meter to the flow rate obtained from a velocity profile measured with a Pitot probe. This aim is achieved by measuring the volumetric flow of air in a pipe using a Venturi and calculating the flow rate from a velocity traverse of a pipe using a Pitot tube. Then comparing the results…
