The Hydrostatic Pressure On Submerged Surfaces system is designed to study and calculate of the pressure force acting on a submerged surface Hydrostatic Pressure On Submerged Surfaces is a simple and completely autonomous equipment that can be easily located in a laboratory without any installation.
It is possible to use liquids of different densities to determine the different exerted forces between them.
With this equipment it is possible to perform the following experiments:
Obtaining and verifying the momentum created by pressure force acting on a submerged curved surface.
Measure and verify the momentum created by the pressing force acting on a submerged flat vertical surface. For that it is necessary to determine both the magnitude of the force and its pressure center. It is possible to distinguish two different cases:
Partially submerged surface.
Complete submerged surface.

The Fluid Statics And Pressure Measurement equipment is designed for the study of static fluid and the measurement of pressures with different types of piezometric tubes and level measurement elements as graduated scales and level meter. One of these water columns has atilting system, so that students can clearly see the effect of the different possible inclinations. The tank and the in water columns have graduated scale for immediate and clear display of the water level that can be measured also by the water level supplied with this system. The equipment includes a transparent tank from where it is possible to pour water through valves and pipes and deliver it in the columns installed in the syst

Pressure variations are made by the rotary vane pump which is provided with needle valves at entry and discharge. A further valve is incorporated at the pump outlet with pressure tappings either side of it to enable differential pressure measurements to be made and plugs are supplied to blank off any connections not in use. The apparatus consists of a series of pressure/vacuum measuring instruments mounted on a wheeled bench with an electrically driven rotary vane pump to provide the necessary pressure and vacuum. The bench also includes a microprocessor based portable digital pressure calibrator for pressures between -1 and 10 bar. The measuring instruments include a sloping, liquid filled manometer reading pressure from 0 to 75mm of water, a vertical manometer reading from 0 to 200 mm of water, a manometer reading from 0 to 760 mm, a pressure transducer with analogue readout and a Bourdon tube gauge scaled - 1 to 2.5 bar for reading both pressure and vacuum.

The bourdon gauge and pressure sensor are mounted on a manifold block with a separate reservoir to contain the hydraulic fluid water for safety and ease of use. Valves enable easy priming, restricted flow of water to demonstrate the application of damping and the connection of alternative devices for calibration.
A bench top unit designed to introduce students to pressure, pressure scales and common devices available to measure pressure.
The DPC consists of a precision ground piston and cylinder with a set of weights giving an operating range of 20 kNm-2 to 200 kNm-2.
The equipment utilises a dead weight pressure calibrator DPC to generate a number of predetermined pressures. This is connected to a Bourdon gauge and electronic pressure sensor to enable their characteristics, including accuracy and linearity, to be determined.
The eccentric shaft is guided onthe drive side by a roller bearing and opposite by a plastic friction bearing. Also cutaway: fuel return with shut-off attenuator, quantity control valve with magnetic coil and filter. The necessary high pressure is generated by a 3-plunger radial-piston pump with the following features: compact construction, stainless steel housing with integrated quantity control valve, fuel-lubricated, shut-off attenuator, max. fuel pressure of 200 bar. The knurled screw can be used to drive the high-pressure pump and one sees how the pump pistons work.

The interaction of these two valves is sometimes difficult for students to grasp. When students can see inside the valve, while the instructor is explaining how it works with the color-coordinated PowerPoint slides, they will quickly grasp the valves function. The Cutaway Pilot Operated Pressure Relief Valve is an application that can be chosen to demonstrate the operation of a pilot-operated pressure relief valve that consists of two direct-operated relief valves.
Educational Advantages:
Allows students to see inside the valve and to quickly grasp the function
Demonstrate the operation of a pilot-operated pressure relief valve
Shows the interaction of two direct-operated relief valves.
