Webflow—flow between two infinite parallel plates separated by distance h, with both the top plate and bottom plate stationary, and a forced pressure gradient dP/dx driving the flow as illustrated in the figure. (dP/dx is constant and negative.) The flow is steady, incompressible, and two-dimensional in the xy-plane. The velocity components are WebSep 11, 2016 · That is the Velocity of the flow at stagnation point is 0, and therefore the stagnation pressure equals to static from the Bernoulli's equation: P (stag) = P (static) + P (dynamic) = P + 0.5 (rho) (V)^2; I don't understand why velocity of the flow at that point is 0. The molecules are hitting the surface as they encounter it with some V (final).
