Textbook Question
Chapter 11, Problem 9P
A submerged body traveling horizontally beneath a liquid surface at a Froude number (based on body length) about 0.5 produces a strong surface wave pattern if submerged less than half its length. (The wave pattern of a surface ship also is pronounced at this Froude number.) On a log-log plot of speed versus body (or ship) length for 1 m/s < V < 30 m/s and 1 m < x < 300 m, plot the line Fr = 0.5.

Aiming a 1.69 in diameter garden hose straight up, forms a “bubbler fountain” that you could easily drink from (but you shouldn’t because of bacteria, etc.). The water flows out the hose and down the sides. If the water has a density of 63.1 lbm/ft^3 and a viscosity of 0.0119 g/cm*s, what is the thickness of the water film (df) (in cm) if the flow rate of water is 6.42 in^3/s? For simplicity, assume the film is thin enough that you can use rectangular coordinates.
