• 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.
• The performance of the heat pipe as a super-conducting device can be studied well in terms of the temperature distribution along the length at a given instant and can be compared with other two members. Nearly isothermal temperature distribution and fast rise of temperature in heat sink tank reveals the heat pipe superiority over the conventional conductors.

• To demonstrate the super thermal conductivity of Heat Pipe and to compare its working with best conductor i.e. Copper pipe & Stainless steel pipe as same material of construction.
• To plot the temperature v/s time response of pipes.
• To plot the temperature distribution along the length of pipes

• 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 enclosure with one side glass to ensure steady atmospheric conditions.
• Temperature Sensors are provided to measure the temperature of each plate and surrounding.
• Electric Supply is given to heaters through separate variacs so that temperatures of both can be kept equal and is me asured with Digital Voltmeter and Digital Ammeter.

• The apparatus is designed to determine the Stefan Boltzman constant.
• The apparatus consists of a hemisphere fixed to a Bakelite plate,the outer surface of which forms the jacket to heat it.
• Hot water to heat the hemisphere is obtained form a hot water tank,which is fixed above the hemisphere. The copper test disc is introduced at the center of hemisphere.
• The temperatures of hemisphere and test disc are measured with the help of temperature sensors.

• Heat exchanger is a device in which heat is transferred from one fluid to another. The apparatus consists of a concentric tube heat exchanger. Hot water flows through inner tube in one direction only and cold water flows through the outer tubes. Direct ion of cold fluid flow can be changed from parallel or counter to hot water so that unit can be operated as parallel or counter flow heat exchanger. Flow rates of hot and cold water are measured using Rotameters. 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.

• Packaging Details: Evaporation Deals With The Concentration Of A Non-Volatile Solute From A Solution By The Removal Of Required Amount Of Volatile Solvent. Usually The Solvent Is Water. By Vaporizing A Part Of The Solvent, Useful Product I.E. The Concentrated Solution Or Thick Is Produced And The Vapour Is Discarded. Long Tube Evaporators Are Usually Used For The Concentration Of Foamy Liquids.The Set-Up Consists Of Stainless Steel Tubes Surrounded By A Stainless Steel Jacket And Fitted With Accumulator. Dilute Solution Is Feed To Tubes. Steam From A Steam Generator Is Supplied To Shell To Concentrate The Dilute Feed Solution To A Desired Level. The Jacket Is Fitted With A Steam Trap And The Condensate Is Collected At The End Of Trap. The Vapours Of Volatile Solvent Are Condensed In A Shell & Tube Type Condenser And The Balance Non-Volatile Solute Collected In The Accumulator Is Recycled Through The Evaporator.

• The setup consists of a brass tube fitted in a rectangular duct in a vertical position.
• The duct is open at the top and bottom, and forms an enclosure that serves the purpose of undisturbed surrounding.
• One side of the duct is fitted with a transparent acrylic window for visualization.
• An electric heating element is kept in the vertical tube that in turns heats the tube surface.
• The heat is lost from the tube to the surrounding air by natural convection.
• The temperature of the vertical tube is measure by temperature sensors and displayed by a Digital Temperature Indicator with multi channel switch.
• The heat input to the heater is measured by a Digital Ammeter and a Digital Voltmeter and is varied by a variac. The tube surface is polished to minimize the radiation losses.
