This equipment is designed to produce and measure free and forced vortices. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

The equipment consists of a clear acrylic cylinder on a plinth. The free vortex is generated by water discharging through an interchangeable orifice at the base of the cylinder and the resulting profile is measured by a combined caliper and depth scale. The forced vortex is generated by a paddle at the base of the cylinder which is rotated by jets of water, and the profile is measured by a series of depth gauges. The velocity at any point in the free and forced vortices may be measured using a pitot tube.

Instruction manual is also included.

This equipment allows measurement of contraction and velocity coefficients as well as discharge coefficient for an orifice discharge. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

It consists of a removable clear acrylic cylinder with adjustable constant head. Water is admitted to the cylinder via a discharge head. An adjustable overflow allows various constant heads for the test. An orifice is fitted at the bottom of the cylinder flush with the base plate. A traverse assembly is provided below the cylinder. Attached to this assembly is a wire and a pitot tube. The wire is to measure the jet diameter hence the vena contracta diameter and the pitot tube is to measure the jet velocity. The velocity head on pitot tube and total head due to tank water level are indicated on manometer tubes. The apparatus rests on adjustable footings and a bull’s eye level is provided.

This equipment provides measurement of force developed by a water jet on different stationary targets. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

The equipment consists of a removable clear acrylic cylinder. Water is supplied through a tube at the bottom of the cylinder and discharged vertically through a nozzle onto a target plate. Each plate maintains the same working distance from the nozzle. A clear acrylic guard is provided to prevent water jet from splashing on the target. Force on the plate pushes its stem upward. Dead weight is then applied on the stem to counter balance the force exerted by the water jet. This balance is indicated by a pointer on a steel rod next to the weight. The apparatus rests on adjustable footings and a bull’s eye level is provided.

This equipment allows determination of coefficient of velocity and coefficient of discharge under various constant heads for two different orifice diameters. Comparison of jet trajectory with that by theory of mechanics can also be made. The equipment is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

The equipment consists of a removable clear acrylic cylinder with sharp edge orifice installed at the lower inside wall of the cylinder. An adjustable overflow allows various constant heads for the test and trajectory of the jet is indicated by probes on the jet path. Heights of the probes are indicated by scales. The apparatus rests on adjustable footings and a level gauge is provided

This equipment measures pressure drop when water flows through a vertical pipe at various flow rates both laminar and turbulent. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

It consists of adjustable constant head water source of removable clear acrylic cylinder for laminar flow. Turbulent flow may be achieved by directly connecting the pipe to the Hydraulics Bench water supply. A water manometer with a vent valve, a hand air pump and a differential pressure gauge are provided for measurement of pressure drop. A valve at the outlet is used to control outlet pressure.

This apparatus is for a study of velocity distribution across pipe section for a water flow in pipe, and for measurement of flow velocity. It is to be used with Hydraulics Bench i.e. HB 100 or HB100N (separately supplied) for a water supply and flow measurement.

The apparatus consists of a total head tube and a static head tube for the Pitot, clear acrylic pipe, inlet and outlet, and an inclined manometer. The total head tube can be moved up or down vertically with a scale for indication of the tube position. Differential pressure is measured by a multiple inclination manometer.

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) for a water supply and flow measurement.

Static pressures at various points along the wall of a transparent Venturi tube are directly measured on a manometer equipped with a vent valve. 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.

The apparatus is for the study of flow over a notched weir. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

Two weir plates, a rectangular notch and two V notches, are provided. Characteristics of flow over the notches can be observed and coefficients of discharge can be determined. The plates are attached to the open channel of the Hydraulics Bench. Water is supplied to the channel via a discharge diffuser and passes through a stilling baffle to smooth the flow. A vernier hook and point gauge is provided to measure the height of water level in the channel.
