Use WC cards alone to define fall velocity.
1
Make fall velocity a function of concentration.
The
functional form is
If concentration is greater than or equal to 1 kg/m3 then
VS(NN) = VS(NN) from WC cards
If concentration is greater than or equal to 0.01 kg/m3 & less
than 1 kg/m3 then
VS(NN) = VS(NN) from WC cards * CONC(NN) ** (4/3)
If concentration is less than or equal to 0.01 kg/m3 then
VS(NN) = 0.02158 * VS(NN) from WC cards *
SQRT(CONC(NN))
