An apparatus and method of flowing a fluid onto an inclined planar surface across the entire width of the slot has a slot capillary number less than 0.04. The slot exit gap S is selected to be less than (I) where S is the slot gap in cm, .mu. is the fluid viscosity measured in poise, 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.
