BERNOULLI VENTURI

Description:	Bernoulli's law for incompressible fluids
Syntax:	/* For an incompressible fluid in a horizontal tube the product of the velocity v of the fluid times the tube cross section A remains constant. That means: The flow velocity varies inversely proportional to the cross section of the tube. / v1 = v2 A2 / A1 /* A1 and A2 stand for the cross sectional areas at the positions 1 and 2. / DeltaP = (1/2) ρ * (v2^2 - v1^2) /* DeltaP means the difference of the static pressure at the positions 1 and 2 measured in a horizontal tube with varying cross section for an incompressible horizontal fluid with density ρ. */
Note:	The general formula of Bernoulli says that the sum of the static and the dynamic pressure plus the potential energy per volume (hydrostatic pressure) is constant along a fluid trajectory: P + (ρ/2)v^2 + ρg*h = constant.
