FAQ

What is Outer surface temperature of a cylindrical wall for a given heat flow rate?
The outer surface temperature of a cylindrical wall for a given heat flow rate formula is defined as the temperature at the outer surface of the cylindrical wall for given heat flow rate through it in the radial direction, inner wall temperature, inner and outer radii, and length of the cylinder and is represented as To=Ti-((Q*(ln(r2/r1)))/(2*pi*k*l)) or outer surface temperature=inner surface temperature -((heat flow rate*(ln(radius2/radius1)))/(2*pi*Thermal Conductivity*length of cylinder)). Inner surface temperature is the temperature at the inner surface of the wall (either plane wall or cylindrical wall or spherical wall, etc.), Heat flow rate is the amount of heat that is transferred per unit of time in some material, usually measured in watt. Heat is the flow of thermal energy driven by thermal non-equilibrium, radius2 is the radius of the second concentric circle or circle, Radius1 is the distance from the centre of the concentric circles to any point on the first/smallest concentric circle or the radius of the first circle, 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 The length of cylinder.
