Plate Heat Exchanger
The apparatus is used for studying heat transfer through a plate heat exchanger under parallel or counter flow conditions.
The unit consists of a plate 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.

Machine Elements and Theory of MachinesComprehensive Geared System
The apparatus is used for studying the acceleration of a geared system as well as geared system efficiency under different gear ratios.
The system consists of three shafts, two stage spur gear unit with two fixed gear and two sliding gear sets. All shafts rest on ball bearings on a steel frame.
The first shaft has a cable drum for weight hanger.
The second shaft has an interchangeable inertia mass. A speed sensor monitors the mass speed at four pulses per revolution.
A motor dynamometer measures the gear system input power. This motor dynamometer drives the first shaft via an electric clutch. Speed is controlled by an inverter.
A mechanical brake dynamometer is attached to the third shaft for measurement of the gear system output power.
For a study of acceleration of the geared system, a weight hanger provides torque on the cable drum and speed sensor can measure inertia mass velocity and acceleration.
The apparatus has a transparent cover with interlocks for safety protection.
Instruction manual is also included.

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.
