This is an open channel with flat top edge for Flow Over A Notch experiment on HB 100G Hydraulics Bench gravimetric or HB 101 Basic Hydraulics Bench.

The unit is to be placed on top of HB 100G or HB 101. Water is admitted to the channel via a discharge diffuser and passes through a perforated sheet. Water is discharged over a detachable weir plate to the end section before draining to the storage tank. A hook and point gauge are placed on the channel top edge for water level measurement. The channel has adjustable footings.

Instruction manual is also included.

This is a simple service unit which provides water supply and flow measurement for use with 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.

This is a service basic unit for providing water supply and flow rate measurement to the bench accessories (separately supply) for specific experiments.

The bench top is flat fiber glass with edge and open channel which can act as volumetric tank. 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.

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 calibrated 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.

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) for a water supply and flow measurement.

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.

This equipment demonstrates primary characteristics of flow in an open channel including flow patterns over or around immersed objects. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

The channel in made of clear acrylic with an undershot weir at inlet and an overshot weir at discharge. Water is admitted to the channel through a cylinder with a stilling baffle to reduce turbulence. A dye injection system is installed at the channel inlet to observe flow patterns around models.

A grid is provided for easy observation of the streamlines.

Instruction manual is also included.

This equipment is designed to study laminar flow in two dimensions. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

Two horizontal plates are placed closely together with seals on side edges.  The top plate is transparent and has a transparent grid to help observe stream line patterns.  This plate is removable to insert or remove models.  The bottom plate has small holes which are connected by valves to a water supply or source and a drain or sink.  Water is admitted through a diffuser at one end and drained at the other end. Stream lines are produced by regulating a flow of dye from a reservoir through a series of very small holes at the upstream end.  

The set rests on adjustable screw supports with bull’s eye level.
