This method involves integrating the continuity and momentum equations over a two-dimensional control volume on a staggered differential grid shown in Figure 1 (S.V.Patankar and D.B.Spalding, 1972). WebConservation of energy tells you that the pressure in the reduced area will be lower because the velocity is increased (speeding a fluid up lowers it pressure, some what counter intuitive because we think of pressure in terms of force not potential energy) Flow rate (Q) = velocity * Area. Q1 = Q2 v1 * A1 = v2 * A2.
