A sump pump is submerged in \(60^{\circ} \mathrm{F}\) ordinary water that vaporizes at a pressure of \(0.256 \mathrm{psia}\). The pump inlet has an inside diameter of \(2.067 \mathrm{in}\). and is \(15 \mathrm{ft}\) below the water surface. Find the maximum possible flow rate before cavitation (vaporization) occurs.
