Hydraulic Studies and AccessoriesBasic Hydraulic Bench
The basic hydraulic bench is a simple service unit which provides water supply and flow measurement for use with other hydraulic bench accessories, for specific experiments (separately supplied).
The bench consists of a storage tank with a drain pipe and a pump with a flow control valve. Flow measurement is by a water meter. The bench top is a stainless steel with an opening where test accessory discharges water to the storage tank. Water from the pump passes through a water meter and discharged to the test accessory by a quick coupling.
The unit is on a steel frame on wheels.
Instruction manual is also included.

Hydraulic Studies and AccessoriesBernoulli’s Theorem Apparatus
Bernoulli’s theorem is applied on flow through a clear acrylic Venturi tube. The apparatus is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied).
Static pressures at various points along the wall of a transparent Venturi tub are directly measured on a manometer equipped with a vent valve and a hand air pump. A movable stainless steel total head probe is also provided. Flow through the Venturi tube is controlled by a valve at the outlet. As a primary flow measuring device, coefficient of discharge for the Venturi tube can also be determined.

Hydraulic Studies and AccessoriesCavitation Panel
This apparatus is for demonstrating the liquid vaporization under low pressure due to high flow velocity such as when water flows through a restriction in a pipe or a water passage. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied).
The test section is a transparent Venturi for vapor observation. Pressure and vacuum gauges are connected to pressure tappings at the upstream end and throat respectively of the test section. The test section and the gauges are mounted on a panel. The panel is intended for use with a Hydraulics bench (separately supplied) or an outside water supply with sufficient pressure and flow rate.

Hydraulic Studies and AccessoriesDead Weight Pressure Tester
The tester is designed to calibrate pressure gauge.
It consists of a precision machined stainless steel piston and cylinder with calibrated weights. The weights are applied on the upper end of the piston rod to generate pressure. The assembly is mounted on adjusting screws with a bull’s eye level. The pressure gauge is connected to the cylinder, thus subject to known pressure and comparison with the gauge reading can be made. Leaking liquid from the cylinder is returned to a reservoir. The cylinder can be simply refilled with liquid from the reservoir without removing the piston.
