Notes:
Bubbles were formed in water when air was passed through a single square-edged orifice which had been drilled in a glass plate. The glass plate was 0.05 in. thick, and the orifice diameter was 1/8 in. The air chambers above the liquid surface and below the orifice plate were varied. The extreme values of these volumes were 0.00975 and 0.195 cu. ft. The air rate through the orifice, Q was as great as 200 × 10-5 cu. ft./sec. Bubble frequencies, f, were as great as 16 sec.-1Both the upper and lower chamber volume influenced markedly the relationship between f and Q. A relationship that predicts sets of upper and lower chamber volumes that result in the same f vs. Q relation is given. A two-parameter equation that gives f as a function of Q is presented.Wettability of the orifice plate and the liquid depth over the orifice plate were also considered as independent variables.
