Investigation on Heat Transfer and Thermal Conductivity Measurement in Lagged Pipe Apparatus

Nowadays more research is going on insulating material to protect our device from damage and to save the input given. If proper insulation is provided, the heat flows from system to surrounding and surrounding to system can be minimized. This all depends on type of insulating material used, so here usage of insulating material varies based on thermal conductivity and application. In this work concentrated on determination of thermal conductivity of two different insulating materials (saw dust and asbestos). This insulating material is logged in-between concentrated pipe and the known amount of heat is supplied, then the calculations were made for find out the thermal conductivity of individual and for the combination of insulating material. And the heat transfers for this combination of insulating material logged between the concentrated pipes are studied.
