Cyclone calculator

An atmospheric system characterized by the rapid inward circulation of air masses about a low-pressure center, usually accompanied by stormy, often destructive weather. Cyclones circulate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. A cyclone is a storm accompanied by high speed whistling and howling winds. It brings torrential rains.

    Formula

    Vradial = [( pparticle - pair ) r w2d2] / ( 18 u )

    Where,
    vradial = Cyclon Radial Velocity
    pparticle = Particle Density
    pair = Air Density
    r = Radial Distance
    w = Rotational Velocity
    d = Particle Diameter
    u = Air Viscosity

    A Cyclone is a violent storm, often of vast extent, characterized by high winds rotating about a calm center of low atmospheric pressure. This center moves onward, often with a velocity of twenty or thirty miles an hour.

    Example:
    Calculate the radial velocity in a cyclone by the given details
    Particle density (pparticle) = 50 kilogram/meter3
    Air density (pair) = 20 kilogram/meter3
    Radial distance (r) = 15 meter
    Rotational velocity (w)= 50 radian/second
    Particle diameter (d) = 25 meter
    Air viscosity (u) = 25 kilogram/meter-second

    Solution:
    Apply Formula:
    Vradial = [( pparticle - pair ) r w2 d2] / ( 18 u )
    Radial velocity (vradial) = 1562500 meter/second
