This lab is equipped with various test rigs to demonstrate laws of thermodynamics and concept of heat transfer, refrigeration, and air-conditioning. The major list of experiments that can be performed in this labs: find the thermal conductivity of liquid by guarded hot plate method, determine the thermal conductivity of the metal rod, calculate the Stefan Boltzmann constant, calculate the thermal conductivity of insulating power, determine the emissivity of the gray surface, determine the overall heat transfer coefficient in finned tube heat exchanger, find out heat transfer coefficient and heat transfer rate from vertical cylinder in natural convection and find out total thermal resistance and total thermal conductivity of composite walls.
