## Bernoulli Pressure LoweringThe linear drop in fluid pressure is according to Poiseuille's law, but the constriction produces and extra drop in pressure according to the Bernoulli Principle.
The liquid column height is a measure of the fluid pressure at that point in the flow tube. The vertical tubes act as manometers. |

## Pressure Drop with LengthThe pressure drop as fluid flows from a container can be modeled by Poiseuille's law. The drop in fluid pressure is indicated by the liquid column heights.
