  # V: air velocity in m/s
  # L: is the characteristic dimension, usually the vertical dimension.  For reference, 
  # a cylinder's characteristic L would be its height, assuming it is standing on its end
  # This L should be the same L as is used for the convective coefficient calculation
  # v: is the kinematic viscosity using function airviscosity(Ta)
