As shown in Fig. P7.41, a thin, flat plate containing a series of holes is to be placed in a pipe to filter out any particles in the liquid flowing through the pipe. There is some concern about the large pressure drop that may develop across the plate, and it is proposed to study this problem with a geometrically similar model. The following data apply.

(a) Assuming that the pressure drop, , depends on the variables listed, use dimensional analysis to develop a suitable set of

dimensionless parameters for this problem. (b) Determine values for the model indicated in the list with a question mark. What will be the pressure drop scale,
