Problem

Water flows steadily through a horizontal pipeline which narrows smoothly from an internal diameter of 5.0 cm to 2.5 cm. At the wider section the speed of water is

1.5\,\text{m}\,\text{s}^{-1}

and the gauge pressure is

1.8\times10^{5}\,\text{Pa}

. Take

\rho_{\text{water}} = 1000\,\text{kg}\,\text{m}^{-3}

. a. (i) Determine the speed of water in the narrower section. b. (ii) Calculate the gauge pressure in the narrower section.
