Enter the cross-sectional area of the nozzle, acceleration due to gravity, height of oil above the nozzle, diameter of the nozzle, and diameter of the pipe into the calculator to determine the flow rate of oil.

## Oil Nozzle Formula

The following formula is used to calculate the oil flow rate through a nozzle.

FR = (A * √(2*g*H)) / √(1 - (d/D)^4)

Variables:

- FR is the flow rate of oil (m³/s) A is the cross-sectional area of the nozzle (m²) g is the acceleration due to gravity (m/s²) H is the height of oil above the nozzle (m) d is the diameter of the nozzle (m) D is the diameter of the pipe (m)

To calculate the flow rate of oil, multiply the cross-sectional area of the nozzle by the square root of twice the acceleration due to gravity times the height of oil above the nozzle. Divide this by the square root of 1 minus the fourth power of the ratio of the nozzle diameter to the pipe diameter.

## What is an Oil Nozzle?

An oil nozzle is a component in oil burners that sprays oil into the combustion chamber at a specific flow rate and spray angle to ensure efficient combustion. It is designed to atomize the oil into tiny droplets, which mix with the air for complete combustion, producing heat. The size and type of nozzle are determined by the capacity of the burner and the characteristics of the oil being used.
