Free and Forced Vortex: Rotating Paddle
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).
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.TYPICAL EXPERIMENTS- Determination of the surface profile of a free and forced vortices Determination of velocity
- Determination of velocity
TECHNICAL DATAOrifice diameters 4 different sizes Distance from center of depth probes 0 to 110 mm. Pitot tube measuring points 3 different radius. Software for data display and analysis by computer (separately supplied). (0 reviews) -

Free and Forced Vortex: Rotating Tank
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).
The equipment consists of a clear acrylic cylindrical tank inside which is another smaller perforated clear acrylic cylinder. The tank is rotated by a small motor. A small hole is provided at the center of the bottom of the tank. A forced vortex is formed when a fixed amount of water is contained in the rotating vessel. A free vortex is formed when water is admitted at the annulus and drain through the bottom hole. A cross bar with scale and a sliding probe holder are provided above the vessel. Water surface profile is measured by a depth probe attached to the cross bar. A transparent tube with built-in pitot probe to measure total head is also attached to the cross bar.

Hydraulic Bench – Gravimetric
This is a service unit which provides water supply and gravimetric measurement for use in conjunction with other accessories for specific experiments (separately supplied).
The bench top is flat fiber glass with a raised edge to hold spilled water and has a quick coupling water outlet, water discharge tube as well as 4 drain holes. The experiment accessories on the bench top discharges water to the measuring tank via a tube. A measuring tank is hung on a cantilever beam on ball bearings. An adjustable tare weight and known weights are provided. When the water in the measuring tank exceeds the set weight, the beam will tilt and the measuring tank automatically discharges to the main storage tank which is drained at the bottom. A pump draws water from the storage tank and supplies to the outlet at the top. The unit is on a steel frame on wheels.
Instruction manual is also included.

Hydraulic Ram Pump
The apparatus demonstrates the principle of a ram pump. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied).
Water from a Hydraulics Bench is supplied to a reservoir with an overflow pipe. Height of the reservoir is adjustable. Water from the reservoir is supplied to the ram pump which has two valves. One valve allows the water to discharge in adjustable pulse controlled by a counter weight. When this valve shuts, the pressure wave will push the water in the pump via a check valve through a non-return valve to the delivery pipe. Water is delivered to a clear graduated cylinder with an adjustable height. A pulse chamber is provided to smoothen the ram delivery.
TYPICAL EXPERIMENTS- Demonstration of the principle of a ramp pump
- Determination of efficiency of the Hydraulic Ram

Hydraulics Bench – Neo
Hydraulic Bench-Neo is a service basic unit for providing water supply and flow rate measurement to the other hydraulic bench accessories (separately supply) for specific experiments.
The bench top is flat fiber glass with edge and open channel. The accessory for the experiment is placed across the channel and discharges water via a drain pipe to the storage tank which has a drain valve. A pump draws water from the storage tank and supplies to the quick coupling outlet at the top. A lid for the drain pipe is provided to trap water in the channel for some experiment. The unit is on a steel frame on wheels.
Instruction manual is also included.

Impact of a Jet
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).
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.
