Multi Heat Exchanger
The apparatus is used for studying of three types of heat exchangers namely-concentric tube, shell and tube, and plate-under parallel or counter flow conditions.
The unit consists of the three heat exchangers and a service module. The module comprises a hot water tank with a transfer pump and instruments for monitoring and control. Changing from one type of heat exchanger to another is by rearranging flexible hoses and changing from parallel to counter flow is by switching two hoses with quick couplings. The unit requires outside water supply.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Comparison of heat transfer for concentric tube, shell and tube, and plate heat exchanger.
- Demonstration of heat transfer under parallel or counter flow.
- Demonstration of batch type heat transfer for jacketed vessel.
- Determination heat transfer coefficient. Effects of flow rate and temperature difference.

Hydraulic Studies and AccessoriesBernoulli’s Theorem Apparatus
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).
Static pressures at various points along the wall of a transparent Venturi tub are directly measured on a manometer equipped with a vent valve and a hand air pump. 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.
TYPICAL EXPERIMENTS- Application of the Bernoulli equation
- Measurement of the meter coefficient of discharge at various flow rates
- Comparison of experimental results with theoretical predictions

Hydraulic Studies and AccessoriesFlow Over a Notch
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).
Three 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.
TYPICAL EXPERIMENTS- Investigation of head against discharge
- Coefficient of discharge for notches
- Demonstration of flow over different notch weirs
TECHNICAL DATAWeir plates Rectangular notch, 60o and 90o V notches. Stainless steel vernier hook and point gauge range 0-150 mm. Software for data display and analysis by computer (separately supplied). (0 reviews)
