The entire experimental set-up is clearly laid out on a metal panel, this is fitted to the Basic Hydraulics Bench. The bench provides the water supply for carrying out the experiment. The experimental set-up comprises a measurement section with a transparent venturi tube, the associated pipework and 2 pressure measuring devices. Six measurement connections o the venturi tube enable the static pressure along the pipe through which the water is flowing to be indicated on a multiple tube manometer. The total pressure is measured with a pitot probe and displayed on a second tube manometer. The flow rate is determined using the volumetric tank on the bench.
