An apparatus and method of flowing a fluid onto an incline planar surface across the entire with of the slot has a slot capillary number less than 0.04. The slot exit gap S is selected to be less thans the fluid viscosity measured in poise, rho is the liquid density measured in gm/cm3, sigma is the liquid surface tension measured in dyne/cm, and Nre is the Reynolds number as defined by Nre=4M/ mu , where M is the liquid flow rate per unit of width measured in gm/sec-cm. The expression for a is defined as 0.981+0.3406 log Nre0.3406. The fluid is flowed through a slot exit.
