In Lumped Heat Capacity System?

The lumped-heat-capacity method of analysis is used in which no temperature gradient exists. This means that the internal resistance of the body (conduction) is negligible in comparison with the external resistance (convection). i.e small h and large k. ... cp = specific heat of the body.

What is meant by lumped heat capacity system?

Definition. The lumped thermal capacity model is the simplest transient heat conduction approach. In this model, the temperature of the solid body is a function of the time only, which means that the temperature is assumed to be spatially independent (uniform).

What is a lumped system?

A lumped system is one in which the dependent variables of interest are a function of time alone. In general, this will mean solving a set of ordinary differential equations (ODEs) A distributed system is one in which all dependent variables are functions of time and one or more spatial variables.
