How to calculate the thermal conductance ( in axial direction ) of a cylinder having length equal to its radius
Thermal conductance is a measure of how easily heat can flow through a material. It is the inverse of thermal resistance and is measured in units of watts per kelvin (W/K).
The thermal conductance of a material can be calculated using the formula G = kA/L, where G is the conductance, k is the thermal conductivity of the material, A is the cross-sectional area, and L is the length of the material.
An axial cylinder is a cylinder with a length that is much greater than its diameter. It is often used to model heat transfer in long, cylindrical objects such as pipes or rods.
To calculate the thermal conductance of an axial cylinder, you can use the formula G = 2πkL/ln(b/a), where k is the thermal conductivity, L is the length of the cylinder, and a and b are the inner and outer radii, respectively.
The thermal conductance of an axial cylinder is affected by several factors, including the material's thermal conductivity, the length and cross-sectional area of the cylinder, and the temperature difference between the inside and outside of the cylinder.
