Automizing Pressure

What is the effect of automizing pressure on tablet weight gain during coating.

At the highest atomizing pressure and lowest gas temperature, the CV of coating thickness is moderately high. The higher atomizing pressure not only produces very small spray droplets but also helps for the impingement and spreading of spray droplets due to its momentum, which consequently increases the surface area and hence facilitates the solvent evaporation. What is CV?
