Smith trays, diameter

Smith recommends obtaining the settling height (tray spacing minus clear liquid depth) by applying the familial Francis Weir formula. For our purposes of rapidly checking column diameter, a faster approach is needed. [Pg.62]

In this equation h is in centimeters of clear liquid, Uq is the hole velocity in m/s, and Q is the orifice coefficient. The hole velocity is calculated from the vapor volumetric flow and the total hole area The orifice coefficient for sieve trays is a function of the ratio of total hole area to active tray area, and of the ratio of tray thickness to hole diameter. This function may be approximated by the equation (Smith, 1963),... [Pg.502]
