How to Evaluate Temperature of Body by Lumped Heat Capacity Method?

Temperature of Body by Lumped Heat Capacity Method evaluator uses Temperature at Any Time T = (exp((-Heat Transfer Coefficient*Surface Area for Convection*Time Constant)/(Density of Body*Specific Heat Capacity*Volume of Object)))*(Initial Temperature of Object-Temperature of Bulk Fluid)+Temperature of Bulk Fluid to evaluate the Temperature at Any Time T, The Temperature of Body by Lumped Heat Capacity Method formula is defined as the function of heat transfer coefficient, surface area of convection, density of object, specific heat capacity of object, volume of body, initial temperature, temperature of convection environment, time taken for temperature change. This type of analysis is called the lumped-heat-capacity method. Such systems are obviously idealized because a temperature gradient must exist in a material if heat is to be conducted into or out of the material. In general, the smaller the physical size of the body, the more realistic the assumption of a uniform temperature throughout; in the limit a differential volume could be employed as in the derivation of the general heat-conduction equation. Temperature at Any Time T is denoted by T symbol.
