A 2.4-in-diameter soap bubble is to be enlarged by blowing air into it. Taking the surface tension of soap solution to be 0.0027 lbf/ft, determine the work input required to inflate the bubble to a diameter of 2.9 in.

The surface tension of solution is given to be σs = 0.0027 lbf/ft.

The work input required to inflate the bubble to a diameter of 2.9 in is × 10–7 Btu.
