11 Determination of Thermal conductivity of Insulating powder
The insulating powder, whose thermal conductivity is to be determined, is fitted in the gap between the two spheres. The heat generated by the heater flows through the powder to the outer sphere. The outer sphere loses heat to atmosphere.

10 Determination of Stefan Boltzmann’s constant
Переглядів 5 тис.3 роки тому
The apparatus is designed to determine the Stefan Boltzmann 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.
9 Determination of Effectiveness of a heat exchanger by Counter flow
Переглядів 1473 роки тому
In counter-flow heat exchangers the fluids enter the exchanger from opposite ends. The counter current design is the most efficient, in that it can transfer the most heat from the heat (transfer) medium per unit mass due to the fact that the average temperature difference along any unit length is higher.
8 Determination of Effectiveness of a heat exchanger by Parallel flow
Переглядів 3443 роки тому
Heat is transferred from the warm fluid through the wall of the inner tube (the so-called heating surface) to the cold fluid. A heat exchanger can also be operated in counterflow, in which the two fluids flow in parallel but opposite directions.This flow arrangement is called parallel flow.
7 Determination of Emissivity
Переглядів 3343 роки тому
This experimental set up consists of two circular aluminium plates, plate one blackened by thick layer of lamp black to form the idealised black surfaces where as the plate 2 is the test plate whose emissivity is to be determined, identical in size and provided with heating coils.
6 Determination of heat transfer co efficient through Natural convection
Переглядів 2573 роки тому
students will able to know to find out heat transfer coefficient by using Natural convection ( takes place during atmospheric air)
5 Determination of Heat transfer co efficient through Forced convection
Переглядів 2303 роки тому
For forced convection tests, a variable-speed fan draws air up through the duct and across the surface. Thermocouples measure the air temperature upstream and downstream of the surface and the temperature at the heat transfer surface
4 Determination Of Heat Transfer Co Efficient Through Pin Fin
Переглядів 4543 роки тому
This setup is designed to study the heat transfer in a pin fin. It consists of cylindrical fin fitted to the base in rectangular duct. A blower is provided on one side of duct to conduct experiments under forced convection heat transfer mode. ... Heat input to the heater is given through variac
3 Determination of Thermal conductivity of the Composite wall
Переглядів 5193 роки тому
The Composite Wall Apparatus is designed for the study of Heat transfer through composite slab made up of different materials. Since each material has different thermal conductivity, heat transferred through each of them is different

Переглядів 8 тис.3 роки тому
The guarded hot plate apparatus uses a steady-state method in order to determine the thermal conductivity of an insulating material. Use of a steady-state method requires that the insulating material be in equilibrium with its surroundings in order for accurate thermal conductivity measurements to be obtained.
1 Determination of Thermal conductivity Lagged pipe
Переглядів 1,8 тис.3 роки тому
he Apparatus is designed to study the lagging phenomenon. The apparatus consists of three concentric pipes, at the axis of which a heating element is positioned. ... Temperature across the lagging material, i.e., temperature of pipe walls for radial outward heat flow are measured by the thermocouples
Introduction to Heat Transfer
Переглядів 203 роки тому
Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species, either cold or hot, to achieve heat transfer.

Thank you sir good explanation
good morning sir ,I am a research scholar and I need to some suggestions regarding thermal insulation .I need the location where this test will be carried ; Thankyou
Is thermal conductivity of concrete can be done with this instrument??
Hi sir.. Is there any availability to visit the test center?
Well done sir 👍 , way to go
Thank you
Hello sir du you conduct the this test for outsiders ???? reply soon ....
Which college u belongs to sir? I want to test thermal conductivity of bricks will u provide facility to do in your laboratory?
Thank you for your extra effort sir ....there is something more work done instead of teaching only your students.... appreciated and it was very clear and useful...
Thank you sir
What was the nature of your sample sir?
