Water flows from a large tank as shown in Fig. P3.90.Atmospheric pressure is 14.5 psia, and the vapor pressure is1.60 psia. If viscous effects are neglected, at what height, h, willcavitation begin? To avoid cavitation, should the value of D1 beincreased or decreased? To avoid cavitation, should the value of D2be increased or decreased? Explain.
