Air Flow and ThermodynamicsCyclone Separator
The equipment is for studying the principle of two phase flow using a centrifugal blower.
Powder material is fed by an agitator and a variable speed screw feeder to a Venturi tube. The material is carried by air in the tube to a cyclone where the velocity is reduced and the material is separated and dropped to the bottom.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Velocity profile of air in the transfer tube using a travelling Pitot.
- Observation of material separation in the cyclone.
- Comparison of theoretical expression with test results for pressure loss and material collection efficiency at each air velocity.
TECHNICAL DATABlower: – Type Centrifugal blower – Maximum air flow rate Over 6 m3/min – Maximum pressure Over 180 mm water Speed control Inverter Cyclone Clear acrylic and discharge tube Accessories - Cyclone dust box
- Filter bag
- Stop watch
- Platform balance
- Beaker
Measuring instruments – Air flow Travelling Pitot with water manometer – Pressure Water manometer for measurement of pressure difference in the transfer tube and the cyclone Software for data display and analysis by computer (separately supplied). Power supply 220 V, 1 Ph, 50 Hz. Other power supply is available on request. (0 reviews) -
Air Flow and ThermodynamicsShell and Tube Heat Exchanger
The apparatus is used for studying heat transfer through a shell and tube heat exchanger under parallel or counter flow conditions.
The unit consists of a shell and 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 and 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.
TECHNICAL DATAConstruction arrangement Insulated stainless steel shell with 7 stainless steel inner tubes Service module consisting of: – Hot water pump. – Heater 3000 W. – Flow meters - Hot water
- Cold water
– Temperature control un . it to limit temperature of hot water to not more than 80°C Software for data display and analysis by computer (separately supplied). Power supply 220 V, 1 Ph, 50 Hz. Other power supply is available on request. (0 reviews)
