Concentric Tube Heat Exchanger
The apparatus is used for studying the heat transfer through a concentric tube under parallel or counter flow conditions.
The unit consists of a concentric tube heat exchanger, and a service module. The module comprises a hot water tank with a transfer pump and instruments for monitoring and control. Parallel or counter flow is by switching cold water hoses with quick coupling. The unit requires outside water supply.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Demonstration of heat transfer under parallel and counter flow.
- Determination of heat transfer coefficient.
- Effects of flow rate and temperature difference.

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

Flow Measurement and Flow StudyParticle Drag Coefficients
The apparatus is designed to study the drag of a particle in a liquid under various Reynold numbers.
This is done by dropping a particle into a vertical liquid column and timing its fall between two points. Particle cross section is no more than 1% of the tube cross section. Various sizes and density of particles are supplied including stream lined shaped objects.
A guide at the top of the tube is provided to minimize disturbance to the liquid. Valves at the bottom of the tubes provide a mean for particle removal with minimum loss of the liquid. The rear panel is translucent with back lighting. This allows clear observation of the particle fall.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Measurement of drag coefficients of sphere under various Reynold numbers.
- Effect of particle shape on rate of fall and drag coefficient.
- Effect of boundary layer separation on motion of sphere.
- Exploration of dynamic similarity.
- Determination of viscosity.
