1. For a soap bubble, the inside pressure must be greater than that outside, and the surface tension actslike a skin to support this pressure difference Ap. The pressure difference is then a function of surfacetension σ and bubble radius R, i.e., Ap = f(o, R). Using Buckingham Pi theorem, find the II group(s)associated with this problem and express them in the form II₁ = (II2, ..., II-r). (Ans: ApR = constant)σ

The objective of the question is to find the dimensionless groups (Pi groups) associated with the…
