Discharge when mouthpiece is running free: Q = 0.5 * a * sqrt(2*g*H);

Discharge when mouthpiece is running full: Q = 0.707 * a * sqrt(2*g*H);

Where,
a = area of the mouthpiece;
g= acceleration due to gravity;
H = Height of the liquid above the mouthpiece;

Running free means the liquid will not able to touch the side of the mouth piece after expansion. Hear length of mouthpiece is dia of orifice.
