\bar{v}^2 = \frac{1}{8} g Q \frac{\lambda^2}{\hp}\, (\nabla - \nabla'),  \end{equation}  so that the average convective velocity can be calculated  \begin{displaymath} \begin{displaymath}\label{eq:velocity}  \bar{v} = \frac{1}{2 \sqrt{2}} \lambda \, \bigg(\frac{g\, Q}{\hp}\bigg)^{1/2} \, (\nabla - \nabla')^{1/2}\\  = \frac{1}{2 \sqrt{2}} g \, \lambda \bigg(\frac{\rho\, Q }{\P}\bigg)^{1/2} \, (\nabla - \nabla')^{1/2}.  \end{displaymath}
