As shown in Fig. P7.29, a jet of liquid directed against a block can tip over the block. Assume that the velocity, \(V\), needed to tip over the block is a function of the fluid density, \(ho\), the diameter of the jet, \(D\), the weight of the block, \(\mathscr{W}\), the width of the block, \(b\), and the distance, \(d\), between the jet and the bottom of the block.

(a) Determine a set of dimensionless parameters for this problem. Form the dimensionless parameters by inspection.

(b) Use the momentum equation to determine an equation for \(V\) in terms of the other variables.

(c) Compare the results of parts (a) and (b).
