Mass Balance

For equilibrium, in addition to the energy minimization, the simultaneous satisfaction of the conservation of elements between a propellant and its products or between two operating conditions is mandatory and this is dealt in this chapter. That is, the total kgatoms of an element between two operating conditions must be equal. For this mass conservation, necessary governing equation is given for a multi-element system involving many product compositions. Related worked examples for typical propellants and their products are added.
