The pitot tube is installed in the water circuit of the HM 500 trainer. The centre axis of the pitot tube is aligned parallel to the flow. The flow impacts the front tube opening head-on. The total pressure (the sum of the dynamic and static pressure) acts on the tube opening. Additionally, the static pressure is measured by a vertical pipe. The pitot tube and vertical pipe are interconnected by one of the differential pressure gauges of the HM 500 trainer. The differential pressure gauge thus indicates the difference between the total pressure and the static pressure. This difference corresponds to the dynamic pressure of the flowing fluid. The flow rate is calculated from the dynamic pressure by applying Bernoulli’s principle and the continuity law.
