The bubble radius at the next extremum (]/2 period later in time) is calculated from the initial value A = A. by either dividing or multiplying. by the ratio ( â J obtained from Table I (by linear interpolation \am/l for the calculations done here). The corresponding air pressure P inside the bubble is then calculated using Equation A18, , (A28) 14. Calculation of the Bubble Period. The bubble period of oscillation T is the product of the dimensionless period, t = F(y,k), given in Table I and the time scale factor C (Equations A15 and A14) Tx = T' x C (A29) Combining (A14, (A21) and (A27), we write for the length scale factor Lx = Ai (1 + X1)]/3 (A30) A-9.
