Mass and Energy Balances In this chapter we will apply the conservation of mass and conservation of energy laws to open systems or control volumes of interest. The balances will be applied to steady and unsteady system such as tanks, turbines, pumps, and compressors. 4.1 Conservation of Mass The general balance equation can be written as


efficiently. Therefore, the mass and heat balance calculation are very vital calculation in a cement process plant. This serves as the basis for the engineering design and the assessment of the production operation equipment performance. Three (3) major steps were adopted in this study using this procedure is highlighted as follows;


Closely related, mathematically, is the "heat balance". Every laboratory test requires a mass balance to describe the results. Mass balance calculations can be subdivided into several sub-categories based on whether the results are time …

Figure 2.1. Mass and energy [email protected] 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. m R = m P + m W + m S (where (sigma) denotes the sum of all terms). m R = m R1 + m R2 + m R3

The overall mass balance equation is: m1+ m2= m3 The total solids balance equation is : m1x1+ m2x2= m3x3 The total water balance equation is : m1(1-x1) + m2(1-x2) = m3(1-x3) The total water balance equation is however NOT a totally new equation. It can be obtained by subtracting the total solids balance equation from the overall mass balance

The heat diffusion equation (in its most general form in which λ, ρ, and c may vary with position) then follows: ∇.( λ∇T) = ρc∂T /∂t (3) It is also necessary to consider heat storage in air masses contained within the building. The model of this process is Q = cp ρaVdT a /dt (4) where Q is the net heat flow into the air mass (W)
