7.1. Using the method of repeating variables prove that the drag force F on a partially submerged body is given by F = V²1²pf (2), where Vis the velocity of the body, I is linear dimension, p is the fluid density, k is the rms height of surface roughness, and g is the gravitational (14) acceleration. 7.2. 11. Under laminar conditions, the volume flow Q through a small triangular-section pore of side- length b and length L is a function of viscosity u., pressure drop per unit length Ap/L, and b. (7) a. Using the pi theorem, rewrite this relation in dimensionless form b. How does the volume flow change if the pore size b is tripled? (4)
