MR-HM115 Hydrostatic Trainer Educational Equipment Fluids Engineering Training Equipment Description • basic experiments in hydrostatics • wide range of experiments • closed water circuit with tankand pump Hydrostatics is the study of fluids atrest. Phenomena occurring as a resultof hydrostatic pressure are analysedand the force effect determined. Hydrostatic aspects play a crucial role in various areas of engineering, such as inplumbing and domestic engineering, inpump manufacturing, in aerospace andin shipping (buoyancy, load on the sidesof a ship). The MR-HM 115 trainer can be used to conduct experiments in the field of hydrostatics, such as ground pressure measurement or demonstrating Boyle’s law. Determining the centre of pressurecompletes the range of experiments. Furthermore, experimental units forstudying capillarity and buoyancy are included. The hydrostatic pressure andsurface tension are measured. Additionally, one experiment uses a Pitot tubeand a tube for static pressure to studythe pressure components in a flowingfluid. To make the functions and processesvisible, the tanks and the experimentalunits use a transparent design. Tanksand pipes are made entirely of plastic. Various pressure gauges are availablefor measuring pressure and differentialpressure of the liquid fluid, such as aPitot tube, tube for static pressure apressure sensor with digital display, twintube manometers or a differential pressure manometer. A diaphragm manometer and a Bourdon tube manometerindicate the pressure of the gaseous fluid. The trainer has its own air and watersupply. The closed water circuit includesa supply tank with submersible pump. Acompressor is included to generate positive and negative pressures for the experiments with air.
