Demonstrates experiments with fins in natural and forced convection and various flow rates, various heat inputs and with fins of different material. Unit consist a pin type fin, heated by a heater, blower draws air over the fin, Thermocouple measures temperature. Fins- Brass, Aluminium and M.S.Control panel with necessary instruments, Air flow duct with blower.The unit is provided with antirust an attractive powder coating

To study the cam profiles and performance of cam & follower system. A cam shaft supported by ball bearing upon which three different types of cam can be mounted. A push rod for follower is supported vertically. A variable speed motor rotates the cam. A dial gauge permits plotting of follower displacement with respect of cam position. Jump speed & effect of weight & spring force on jump speed can be studied.

Journal Bearing Apparatus available was with oil manometers which possessed so many problems, mainly air bubbles, overflow of oil, due to which full pressure could not be developed. Also bearing having very large radial clearance presented question about application of theory itself. Hence, we developed a journal bearing apparatus with a practical radial clearance of 0.2 mm and with a pressure gauge. Clearance of 0.2 mm eliminated question about application of theory and use of rotatable pressure gauge avoided air bubble problem & also it allowed development of pressure fully. Also, the apparatus allows accurate determination of friction torque and determination of oil flow. Rotating pressure gauge gives polar pressure distribution. The graph of coefficient of friction vs. bearing modules can be drawn which demonstrates the boundary and fluid film lubrication.The apparatus is accurate and simple means to study a practical journal Bearing.
