FAQ

What is Critical Radius of Insulation of a Cylinder?
Critical Radius of Insulation of a Cylinder is the radius of insulation at which there is maximum heat transfer and increase or decrease in its value will lead to an overall decrease in heat transfer and is represented as Rc=k/h or Critical Radius of Insulation=Thermal Conductivity/External convection heat transfer coefficient. Thermal Conductivity is the rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance and External convection heat transfer coefficient is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, ΔT) in case of convective heat transfer.
