Problem

Water flows steadily through a horizontal pipe that tapers from an internal diameter of

10\,\text{cm}

5\,\text{cm}

. The pressure at the larger section is

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

. If the discharge through the pipe is

0.020\,\text{m}^{3}\,\text{s}^{-1}

, determine the pressure at the smaller section. (Take

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

and

g=9.8\,\text{m\,s}^{-2}
