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. 

Instruction manual is also included.

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.

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.

This equipment provides laminar, transitional, and turbulent flow as predicted by Osborne Reynolds. 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 tank which is partitioned in half. Water is admitted at the bottom of one half through a diffuser and stilling material. The other half of the tank has an adjustable over flow pipe with a discharge at the bottom. Water from the tank is admitted into a clear horizontal shell inside which is a bell entry with a test pipe. Flow through the test pipe is controlled by a discharge valve. A dye injection system needle discharges the dye to the bell mouth and flow pattern in the test pipe can be observed.

This equipment provides laminar, transitional, and turbulent flow as predicted by Osborne Reynolds. 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 an adjustable overflow pipe. Water is admitted at the bottom of the tank through a diffuser and stilling materials, and is discharged via a bell mouth transparent vertical test pipe with a flow control valve at the end.  Flow rate is measured by a measuring cup. A dye injection system is installed on top of the acrylic cylinder tank and flow patterns in the pipe can be observed against a white background plate.
