MR-HM 150.05 Hydrostatic Pressure in Liquids Teaching Equipment Hydraulic Bench Description • determination of forces on surfaces under hydrostatic pressure
The weight of fluids at rest causes apressure that is known as hydrostaticpressure or gravitational pressure. Thispressure acts on any area that is incommunication with the fluid, exerting aforce that is proportional to the size ofthe area. The effect of hydrostatic pressure ishighly important in many fields of engineering: in shipbuilding, in hydraulic engineering when designing locks and weirs,in sanitation and building services. The HM 150.05 experimental unit offers typical experiments to study hydrostatic pressure in liquids at rest. The effect of the hydrostatic pressure of watercan be clearly shown at different waterlevels and angles of inclination. The experimental unit consists of atransparent, tilting water tank with ascale for measuring volumes. Anotherscale is used to adjust the angle of inclination of the water tank. The device is balanced by a lever arm using differentweights and the compressive forcemeasured.
