Consider flow from a water reservoir through a circular hole of diameter D = 0.16m at the sidewall at a vertical distance H from the free surface. The flow rate through an actual hole with a sharp-edged entrance (?? = 0.47) is considerably less than the flow rate calculated assuming “frictionless” flow and thus zero loss for the hole. Disregarding the effect of the kinetic energy correction factor, obtain a relation for the “equivalent diameter” of the sharp-edged hole
