Water (density

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

) flows through a horizontal pipe that widens from cross-section

A_1 = 1.5 \times 10^{-4}\,\text{m}^2

A_2 = 6.0 \times 10^{-4}\,\text{m}^2

. The pressure at the wider section exceeds that at the narrow section by

2.0 \times 10^{3}\,\text{Pa}

. Calculate the speed of water at the wider section.
