HOW DO SCIENTISTS APPROACH PROBLEMS

Illustrative Example: A Blending Process. An unsteady-state mass balance for the blending system: or. where w1, w2, and w are mass flow rates. The unsteady-state component balance is: The corresponding steady-state model was derived in Ch. 1 (cf. Eqs. 1-1 and 1-2). The Blending Process Revisited. For constant ρ, Eqs. 2-2 and 2-3 become: ................
