Pelton turbine test rig of blower casing fitted to a variable speed motor. Three different type of impellers can be fitted over the shaft. Air discharge is measured by venturimeter. The impeller can be rotated at different speed and performance of blower can be estimated at different speed and discharge heads.

Heat Transfer Lab Equipment Heat Transfer in Natural Convection, Heat Transfer in Forced Convection Apparatus, Critical Radius of Insulating Material, Heat Transfer in Agitated Vessel, Plane Finned Tube Comparator Type.

MICROTECH apparatus enables the students to study the interesting phenomenon of heat pipe & to compare its performance with other pipes. The apparatus consists of a heat pipe made up of stainless steel, evacuated and partially filled with distilled water, a copper pipe and stainless steel pipe of same sizes. The pipes are heated at one end and water tank is provided at the other end of the pipe to take out the heat. Thermocouples are provided along the length of pipes so that nearly isothermal operation of heat pipe as compared to other conductors can be demonstrated. Rapid rise of water temperature in the tank around heat pipe demonstrates super conductivity of heat pipe as compared to copper pipe as good conductor of heat and to stainless steel pipe as same material of construction.Heat Pipe - Stainless steel pipe size 25 mm. dia. 450 mm. long, with both side closed, evacuated and filled with distilled water along with fine stainless steel mesh inside the wall.

Forced vortex apparatus of transparent cylinder mounted on rotatable base plate. When water is directed tangentially in the cylinder, free vortex is formed. A pointed tracer provided with scale enables to plot the water surface profile. The cylinder can be rotated with the help of small motor, so that forced vortex is formed. The forced vortex can be observed at different speeds.

Critical Heat Flux Apparatus MICROTECH apparatus consists of a nichrome wire immersed in water. The nichrome wire is heated by passing current through it. Input to nichrome wire is controlled by a dimmer stat. As one goes on increasing wire input current increases and at critical heat flux the wire brakes, which is measured on the meter. A magnifying glass & a lamp is provided to visualize natural convection and pool boiling also.

The apparatus is designed to study the cam profiles and performance of cam and follower system. The apparatus consists of a cam mounted shaft supported by ball bearings upon which three different type of cam be mounted. The push rod for follower is supported vertically which can adapt three different types of followers cams and followers can be changed easily. A variable speed motor rotates the cam. A dial gauge provided permits plotting of follower displacement with respect to cam position. By operating the system at different speed, jump speed can be found and also the effect of weight and spring-force on jump speed can be studied. Jump can be visualized also with the help of stroboscope. (It is not supplied with the product)

MICROTECH apparatus consists of transparent flow channel through which water is made to flow. The velocity of water changes as cross sectional area of channel changes. The changes of head are measured with manometric tubes connected at various tappings along the length of channel. Thus the Bernoullis theorem can be verified by calculating the energy and head of water at different sections.Transparent acrylic flow channel, 75 cm long. (ConvergentDivergent type)

Air Conditioning Test Rig works on simple vapour compression refrigeration cycle using R 134a as a refrigerant.The system is fabricated such that student can study all the air conditioning processes. It is also useful to understand working of all the components of system, their performance and control etc. All the components are mounted on the display board, so that students can observe their working easily.
