Thermal time constant equation: The thermal time constant is given by the following equation, `\tau_{th}=\frac{\rho VC}{hA_{S}}` Where, = Density of the body V = Volume of the body C = Specific heat of an object h = Convective heat transfer coefficient As = Surface area of the body Therefore thermal time constant depends on the above factors. At this point, we have to add a new mechanism, which is known as advection (the transport of a substance by bulk motion). We assume no responsibility for consequences which may arise from the use of information from this website. The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate.
