PART 3 INTRODUCTION TO ENGINEERING HEAT TRANSFER

For one-dimensional heat conduction (temperature depending on one variable only), we can devise a basic description of the process. The first law in control volume form (steady flow energy equation) with no shaft work and no mass flow reduces to the statement that ΣQ& for all surfaces = 0 (no heat transfer on top or bottom of figure 2.2).

Mass and Energy Balances

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

Mass and Energy Balances

Mass balance problems can be divided into those that are in steady state and those that are non-steady state. A steady-state situation is one in which things do not change with time---the incoming concentration and flow rate are constant, the outgoing flow rate is constant, and therefore the concentration in the control volume is constant
