This is a floor standing open channel which can be quickly converted into a closed channel for studying both open and closed channel flow. It is to be used with HB100 Hydraulics Bench (separately supplied)

The channel has transparent side walls with tanks at both ends for supplying water to and receiving water from the channel. Each tank has a flow control valve to control flow and water level in the channel. The inlet tank has a stilling arrangement. A removable lid is placed on top of the open channel to convert it to a closed channel. The mid section of the channel bed is adjustable for demonstration of Bernoulli theorem in closed conduit flow.

Accessories and measuring instruments are provided for the flow study.

Instruction manual is also included.

This is a bench top self contained water circulating unit for studying the various flow measuring instruments including primary flow measuring devices.

The flow measuring instruments are connected in series and all except the measuring tank are arranged on a water proof panel.

Measurement of flow by a primary flow measuring devices is by coefficient of discharge which is determined from a pressure drop across the device and a flow rate. Flow rate is obtained from a water meter reading and a stop watch. The pressure drop is measured by deferential pressure using manometers. Pressure tapping is by small ball valves with quick connection. Water tanks are behind the panel. Flow rate is varied by a flow control valve.

Instruction manual is also included.

This apparatus is used to study the effects of both pipe surge and water hammer using two separate straight pipes with a constant head tank.

Pipe surge employs a clear acrylic surge shaft to demonstrate gradual velocity change, hence pressure rise and its oscillations by slow valve closing. Water hammer employs a quick closing valve and two pressure sensors-one next to the valve and another further away. Sudden rise in pressure on quick closing valve can be demonstrated on a computer (separately supplied). The equipment is to be used with Hydraulics Bench (separately supplied).

Instruction manual is also included.

This equipment is designed to measure the flows and pressure drops in a wide range of pipe network configuration e.g. individual pipes, series pipes, parallel pipes, doubling pipes, and ring main.

Pressure drops is measured by manometers. Fittings connection is by screwed coupling with “O” rings. Pressure tapping is by small ball valves with quick connection. The apparatus and accessories are attached on a panel to the Hydraulics Bench.
