Jet from perpendicular opening 

Jet discharged from a rectangular opening along a flat wall (3- dimensional flow).

By approximation:

(equation 1)

with

(equation 2)

in which:

A: area of the in-flow opening [m]
B: width of in-flow opening [m]
h: height of in-flow opening [m]

The figure below illustrates the situation.

Further:

(equation 3)

and

(equation 4)

The equations are valid for the area of the developed flow. For this it is assumed that: x > MAX (6h,6B).
