Engineering Riddle – No. 5 (Fluid Mechanics) “Dimensionless”
I’m a fraction made of forces, comparing different strength I have no final units, only characteristic length I sample speed and weight and size, these are the things I measure My subject as it ebbs and flows, changes shape forever On top I show inertia, the power to keep things steady Below I measure thickness, stickiness and eddy In pipe or duct or channel, o’er wings be smooth, or rough I’ll tell you dominant motive, whether sheering’s weak or tough What am I?
