HM 115 Hydrostatics Trainer Show data sheet (pdf file) Print page
Technical Description

  Hydrostatics is the study of fluids at rest. Phenomena occurring as a result of hydrostatic pressure are analysed and the force effect determined. Hydrostatic aspects play a crucial role in various areas of engineering, such as in plumbing and domestic engineering, in pump manufacturing, in aerospace and in shipping (buoyancy, load on the sides of a ship).
  The 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 pressure completes the range of experiments. Furthermore, experimental units for measuring the hydrostatic pressure, surface tension and buoyancy and for studying capillarity are also included. Additionally, one experiment uses a pitot tube to study the pressure components in a flowing fluid.
  To make the functions and processes visible, the tanks and the experimental units use a transparent design. Tanks and pipes are made entirely of plastic.
  Various pressure gauges are available for measuring pressure and differential pressure of the liquid fluid, such as a pitot tube, a pressure sensor with digital display, twin tube manometers or a differential pressure manometer. A diaphragm manometer and a Bourdon tube manometer indicate the pressure of the gaseous fluid.
  The trainer has its own air and water supply. The closed water circuit includes a supply tank with submersible pump. A compressor is included to generate negative pressures for the experiments with air. 

  The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
