Mass and Energy Balances - NCSU

 · 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
