Francis Turbine is a reaction turbine, which was developed by an English born American Engineer Sir J. B. Francis. The water enters the turbine through the outer periphery of the runner in the radial direction and leaves the runner in axial direction and hence it is called a mixed flow turbine. As the water flows to the runner, a part of pressure energy goes on changing into kinetic energy. Thus the water through the runner is under pressure. The runner is completely enclosed in a air tight casing and the casing & runner is always full of water.

The present set-up consists of a runner. The water is fed to the turbine by Means of Centrifugal Pump, radially to the runner. The runner is directly mounted on one end of a central SS shaft and other end is connected to a brake arrangement.

It is a super-conducting device and involves the transfer of heat by boiling and condensation of a fluid and hence transfer of heat takes place under nearly isothermal condition. In this apparatus the comparison of heat pipe with the copper pipe as good conductor of heat and with the stainless steel pipe as same material of construction is made. It consists of three identical cylindrical conductors in respect of geometry. One end of these is heated electrically while there are small capacity tanks acting as heat sinks at the other end. The unit consists of a heat pipe a copper pipe and a stainless steel pipe. Temperature sensors are embedded along the length to measure the temperature distribution and the heat transfer rate is noted in terms of the temperature rise in the heat sink tanks.

The set-up is designed to demonstrate and stimulate the moisture removal by heat under forced draft action created by hot air stream and shower of moist solid due to rotary action of dryer drum.

The set-up consists of a long cylindrical shell slightly inclined towards the outlet rotating at low RPM. Counter current hot air from blower passes through heating chamber to produce hot air works as the drying agent entered from one side of the rotating shell and leave from other side removes the moisture from the moist solids. High moisture content feed enters from one end of the shell and low moisture content product discharges from the other end of shell. As the shell rotates internal flights lift the solids and shower them down through the interior of the shell. This action increases the contact of wet solid against hot-air making the dryer very effective.

An arrangement is made to vary and measure the airflow rate. A digital temperature controller is used to control and measure the temperature of air stream

Shell and Tube Heat Exchanger are popular in industries because they occupy less space and offer reasonable temperature drop. The apparatus consists of fabricated SS shell, inside which copper tubes with baffles on outer side are fitted. This is two-pass heat exchanger so that hot water passes to one end of shell through the tubes and returns to another end through remaining tubes. The cold water is admitted at the one end of shell, which passes over the hot-water tubes. Valves are provided to control the flow rates of hot and cold water. Flow rates of hot and cold water are measured using Rota meters. A magnetic drive pump is used to circulate the hot water from a re-cycled type water tank, which is fitted with heaters and Digital Temperature Controller.

The setup is designed to demonstrate principles of distillation in a Sieve Plate Column.

The column is made of stainless steel material with seven sieve trays. An electrically heated re-boiler is installed at the bottom of the column. The bottom product is collected in the tank. The vapors form the top of column are condensed in the shell and tube type condenser by circulating cooling water supplied by laboratory overhead tank. The condensate is divided into reflux and distillate by automatic reflux divider and R/D Ratio can be varied. Reflux is fed back to the column and distillate is received in a receiving tank. The complete column is insulated for minimizing the heat loss. Instrumentation is done for pressure & temp. Measurement wherever is necessary

The ems-8 is a micro controller based electromagnetic sieve shaker. The movement produced is tri-dimensional, combining a vertical movement with a rotation of the material to be shifted on the surface of the sieve.  

the shaker is powered by an electromagnetic drive which has no rotating parts, making it maintenance free and extremely quiet in operation. The vibratory action produced by the power unit moves the sample all over the sieve in a unique way producing faster, more efficient sieving, while the rapid vertical movements also help to keep the apertures free from blocking.  

the ems-8 is very suitable for sieving of high density products and for dry and wet sieving analysis. The unit has been designed for user friendly operation and supports a menu driven 16x2 character lcd display. The unit is robustly built and can be used in laboratories or at site. It is compact and portable.  

the ems-8 is ideally used as a particle profile / size analyzer for the more.

Single Stage Air Compressor Test Rig consists of a single stage reciprocating type air compressor driven by 1 HP motor through a belt.
