The drag force d that a fluid exerts of a thin vertical rectangular plate is function of the plate height h, plate width w, the fluid dynamic viscosityp, the fluid density p, and the fluid flow velocity v. using buckingham pi theorem, determine all the dimensionless products (ls) of the problem.

Fluids at rest possess no flow energy. a)- true b)- false
