Going to have to add an air density variable, which means that the user will have to figure that density out when he/she does a coastdown run set. Was tempted to include "
locust density" as a nod to
dcb...
Going to also have to include the viscosity component for the solver. This will be the equation I will use inside the solver ->
F(drag) = F(rr) + F(viscosity) + F(aero)
F(rr) = m * g * C(rr)
F(aero) = (rho) * C(d) * A * (v^2) / 2
F(viscosity) = C(viscosity) * v
F(viscosity) is not very large, but it is significant, and it will have an effect on calculating C(d) if it is ignored.
