Chapter 7, Problem 7.13(choose chapter or problem)
The drag, \(\mathscr D\), on a washer-shaped plate placed normal to a stream of fluid can be expressed as
\(\mathscr D=f(d_1,d_2,V, \mu, \rho)\)
where \(d_1\) is the outer diameter, \(d_2\) the inner diameter, V the fluid velocity, \(\mu\) the fluid viscosity, and \(\rho\) the fluid density. Some experiments are to be performed in a wind tunnel to determine the drag. What dimensionless parameters would you use to organize these data?
