ABSTRACT:
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 than ##EQU1## where S is the slot gap in cm, .mu. is the fluid viscosity measured in poise, .rho. is the liquid density measured in gm/cm.sup.3, .sigma. is the liquid surface tension measured in dyne/cm, and N.sub.re is the Reynolds number as defined by N.sub.re =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 N.sub.re.sup.0.3406. The fluid is flowed through a slot exit.
