### Mass Balance Equation - an overview |

Mass balance equations are commonly used for quantifying chemical reactions in river networks. The governing equation for steady-state mass fluxes in a stream reach is extended by adding a term for first-order reaction and the equation is rearranged by moving terms to the left side of the equation to express the spatial change in mass fluxes as a function of distance:

### Mass and Energy Balances

Mass balances are developed and applied in some detail in the following section, after which the concept of the energy balance is presented and applied. Mass Balance. This principle of conservation of mass is extremely useful. It means that if the amount of a pollutant somewhere (say, in a lake) increases, then that increase cannot be the result of some ``magical'' formation

### Calculation with Heat Transfer with Examples

Calculations of Heat Transfer Conservation of energy theorem is also applied to heat transfer. In an isolated system, given heat is always equal to taken heat or heat change in the system is equal to zero. If two objects having different temperatures are in contact, heat transfer starts between them. The amount of heat given is equal to the amount of heat taken.
