Oil of density

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

flows steadily through a pipeline. At section 1 (ground level) the pipe area is

6.0\times10^{-4}\,\text{m}^2

, the gauge pressure is

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

and the speed is

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

. The pipe then rises to section 2 which is

2.0\,\text{m}

higher and has an area of

3.0\times10^{-4}\,\text{m}^2

. Calculate the gauge pressure at section 2.
