Cyclone Separator Efficiency (Particle Removal) Formula & Calculator

Particle Removal from Gas Streams Calculation

dpc - Diameter of particle collected with 50% efficiency (m)
dp - Diameter of particle of interest (m)

Cyclone collection efficiency (particle removal) calculator - formula & step by step calculation to measure fractional particle collection efficiency to remove the dust from industrial gas streams. η = 1/(1 + (dpc + dp)2). The diameter of particle collected with 50% efficiency dpc in m & diameter of praticle interest dp in m are the key elements of this calculation. η is defined as the seperation of fraction of particles of a given size due to the force caused by the spinning gas stream in a cyclone.


In environmental engineering, the below formula is used to calculate the separation of fraction of particles of a given size in cyclone. This calculator provides step by step calculation for each set of inputs let the users to understand how to perform such cyclone collection efficiency calculations manually for environmental impact analysis
formula to calculate cyclone fractional particle collection efficiency

In the field of environmental engineering, while working with the design & analysis of industrial gas streams, sometimes it's important to analyse the particle removal from industrial gas streams. The above formula & the step by step calculation may useful for users to understand how the values are being used in this η calculation, however, when it comes to online for quick calculations, this collection efficiency (particle removal) calculator helps the user to perform & verify such calculations as quick & easy as possible.
