The Morton number Mo, used to correlate bubbledynamics studies, is a dimensionless combination of acceleration of gravity g, viscosity p, density p, and surface tension coefficient Y. If Mo is proportional to g, find its form. 1 1 Solution: The relevant dimensions are {g) = {LT~), {p) = {ML T }, { p ) = {IvL~}, and { Y } = {MT"). To have g in the numerator, we need the combination: Solve for a = 4, b = 1, c = 3, or: Mo =  gp4 Ans. py3...
