The apparatus has been designed to introduce students to the fundamental characteristics of the behavior of the particle system, in particulars the relationship between the drag coefficient of falling particles and their Reynolds number value. Particles covering a range of sizes and densities are supplied and the experiments are conducted by allowing single particles to fall through a number of different liquids contained in a vertical glass tube. The rate of fall of the particle is determined by timing their passage between two marks on the walls of the glass tubes. Observation of the particle movement is aided by the provision of a shielded fluorescent tube light mounted on the backboard. Particles can be removed from the bottom of the tubes without the necessity of draining the liquid. A valve system is provided at the bottom of each tube to allow the particles to be removed with the minimum loss of liquid.

Condensation is a phase change heat transfer process occurring in many industrial applications, such as in steam power plants, refrigeration plants etc. Thus this is one of the important heat transfer process present in mechanical and chemical engineering application. The condensation of Vapour on a surface is of two types: 1. Drop wise Condensation. 2. Film wise Condensation. This set up is designed for finding heat transfer co-efficient of two types of condensation and for visualization of these processes. It consists of a vertical frame.

Water level indicator is provided to safeguard the heater. Condensate is measured by measuring cylinder

The present Set-up is designed to measure the emissivity of test plate. The test plate comprises of a mica heater sandwiched between two circular plates. Black plate is identical with test plate, but its surface is blackened. As all the physical properties, dimension and temperature are equal; heat losses from both plates will be same except radiation loss. Hence the input difference will be due to difference in emissivity. Both plates are supported on individual brackets in a wooden enclosure with one side glass to ensure steady atmospheric conditions. Temperature Sensors are provided to measure the temperature of each plate and surrounding. Supply is given to heaters through separate variacs so that temperatures of both can be kept equal and is measured with Digital Voltmeter and Digital Ammeter

Helical coils are used for heating or cooling in process tanks. When a fluid flow through a curved tube, centrifugal force acting upon the various elements of fluid moving with different velocities causes secondary circulation. Secondary flow results in higher heat transfer characteristics. Further secondary flow stabilizes the laminar flow leading of a higher critical Reynolds number for transition from laminar to turbulent flow.

Mixed liberated particles can be separated from each other by floatation if there is sufficient difference in their wettability. The floatation process operates by preparing a water suspension of a mixture of relatively finely sized solids. This is usually done in an agitated chamber open at the top. Fine bubbles of air are then dispersed through the agitated suspension to form a froth that rises to the top of the chamber. Particles that are radially wetted by water (hydrophilic) tend to remain in the water suspension. Those particles that are not easily wetted (hydrophobic) tend to be collected at the air bubble-water interface and rise to the surface attached to air bubbles. Thus differences in the surface chemical properties of the solids are the basis for separation. The set up consists of a agitated chamber open at the top. In the chamber, an impeller coupled to a shaft is fixed in a stationary diffuser. Low-pressure air is allowed to enter in the stationary diffuser through the air passage provided with the agitator. The collector-coated mineral particles adhere to the rising bubbles and are carried to the top of the cell to be removed in the froth product. The stepped pulley arrangement is done for moving the agitator at three different speeds. The set-up is complete with all accessories.
