I What is this equation called?

  1. May 10, 2018 #1
    wind velocity
    • E = V3rho, where E is erosivity , V is velocity and rho is air density
    • thus the erosivity of wind is an exponential function of wind velocity, i.e. if the wind velocity doubles, the wind is 8X more erodible or, if it triples, the wind is 27 times more erodible
    • that is why we observe massive wind erosion (dust) with a significant increase in wind speed
    Is there a name for the equation in bold?

    No, that would need the wind speed in the exponent. Otherwise it is not an exponential function. It is a polynomial function here.

    I don't know if that equation has a special name.
