# Exclusively for Cement Process Engineers Cyclone efficiency calculator – Eng Nael Shabana

## Cyclone efficiency checking by using Standard Efficiency Formula

you will have to input Cyclone data :

Entry area dimension |

Immersion tube dimensions:

Cylindrical part dimension:

Conical part dimension:

Temperature at Cyclone inlet:

Pressure at Cyclone inlet:

density of material:

density of gases(NTP):

Gas flow rate at Cyclone inlet:

then

Calculations | |||

Viscosity of air at temp: | 0.000023 | kg/m.s | |

Density of the gas: | 331 | kg/m3 | |

Number of revolutions in the outer vortex (N_{e}) | 9 | ||

Velocity at inlet | 36.35 | m/s | |

Gas residence time in outer vertex | 2.18 | sec | |

Cut off size of particle | 12.82 | microns |
