Figure 4.1: Mass and Energy Balance. The law of conservation of mass leads to what is called a mass or a material balance. Mass In = Mass Out + Mass Stored Raw Materials = Products + Wastes + Stored Materials. Σm R = Σm P + Σm W + Σm S (where Σ (sigma) denotes the sum of all terms). Σm R = Σm R1 + Σm R2 + Σm R3 = Total Raw Materials Σm
