A consulting firm is asked to perform a study of pipe flow. A fluid flows at velocity, V, through thepipe of diameter, D. An orifice plate containing a hole of diameter, d, is placed in the pipe (thismeans the pipe diameter is essentially reduced to d at this location). It is desired to study thepressure drop, AP, across the plate. Assume that AP = f(D, d, o, V). Determine a suitable set ofpi terms.
