Nozzle Air Velocity

The nozzle air velocity describes the speed of air flowing out of a nozzle under pressure. A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits an enclosed chamber or pipe.

The air velocity increases with the square root of the nozzle diameter, pressure and the reciprocal of the nozzle length.

Formula

QuantityVariable["V", "Speed"] == Sqrt[(Quantity[3125/18, "Feet"^4/("OuncesForce"*"Seconds"^2)]*QuantityVariable["D", "Diameter"]*QuantityVariable["P", "Pressure"])/QuantityVariable["L", "Length"]]

symbol description physical quantity
V air velocity "Speed"
D nozzle diameter "Diameter"
L nozzle length "Length"
P pressure "Pressure"
