Transport equations : Mass and heat balances

The transport equations for mass and heat are obtained from conservation laws of mass, on one hand, and energy, on the other hand. We consider a volume V xed in space and bounded by a surface @V = Sand we write the balance between the change of mass or energy within V and the net uxes of mass or energy crossing the bounding surface S.
