One Term Approximation of Transient Conduction

by Learn ChemE (Chem. Eng. Videos)

Transient conduction that cannot be modeled as lumped capacitance is demonstrated using a sphere that is suddenly immersed in a hot gas. The temperature at a certain time is calculated using the one-term approximation of the exact solution. This temperature is compared to the one gotten if lumped capacitance is assumed.
