General heat balance equation of a calorimetric system

General heat balance equation of a calorimetric system 

The amount of heat dQij i) exchanged between domains j and i in the time interval dt is proportional to the temperature difference of these domains the heat loss coefficient Gj ij = 1,2. N i j) is the proportionality factor  

The condition Gj=G is fulfilled. The amount of heat dQjo(t) exchanged between domain j and the environment in time interval dt is equal to 

The amount of heat dQ/t) generated in domain j in time interval dt is equal to the sum of the heat accumulated in this domain dQ (t) and the heat exchanged between this domain and the remaining domains and the environment dQ t). Thus

The differential equation Eq. (1.148) is called the general heat balance equation of domain j, and the set of these equations is the general heat balance equation of a calorimetric system. The heat balance equation Eq. (1.147) describes in general form the courses of the heat effects in a calorimeter of any configuration of domains and any localization of heat sources.
