In the widest part of the horizontal pipe oil is flowing at a rate of \( 2 \mathrm{~m} / \mathrm{sec} \). Determine the
P speed of the flow of oil in the narrow part of

W the tube if the pressure difference in the broad and narrow parts of the pipe is \( 0.25 \rho_{\text {oil }} \) g.
(1) \( 9 \mathrm{~m} / \mathrm{s} \)
(2) \( 6 \mathrm{~m} / \mathrm{s} \)
(3) \( 3 \mathrm{~m} / \mathrm{s} \)
(4) \( 1 \mathrm{~m} / \mathrm{s} \)
