Flow calculation as a function of working pressure

Description

This is a function to determine the flow rate of a spray nozzle as a function of the working pressure

Usage

flowpres(q1, q2, p1, p2)

Arguments

q1	Nozzle flow 1 (L/min)
q2	Nozzle flow 2 (L/min)
p1	Nozzle pressure 1 (bar)
p2	Nozzle pressure 2 (bar)

Details
