Webdenotes the distance above the boundary. The fluid velocity at the boundary (y = 0) is zero. At some distance above the boundary the velocity reaches a constant value, U∞, called the free stream velocity. Between the bed and the free stream the velocity varies over the vertical coordinate. The spatial variation of velocity is called shear. WebBulk Air Flow in a Duct • Air movement always follows the pressure gradient – Flow goes from higher (abs) pressure to lower (abs) pressure regions • This is the effect of molecular-level collisions – More energetic molecules collide with neighbors, and increase the velocity of the surrounding molecules (and pressure)

WebResistance is how hard the vessel is trying to stop the flow of fluid. It's made up of how small the vessel is, and the friction along the sides. Flow is the amount of fluid that's passing through the vessel over an amount of time. It's determined by how much the pressure can push against the resistance. ( 4 votes)

WebFlow velocity. The solution of the equations is a flow velocity.It is a vector field—to every point in a fluid, at any moment in a time interval, it gives a vector whose direction and magnitude are those of the velocity of the fluid at that point in space and at that moment in time. It is usually studied in three spatial dimensions and one time dimension, although … WebExample - The Dynamic Pressure in a Water Flow.
