Problem

Water rises vertically through a pipe of uniform area. At point A (bottom) the gauge pressure is

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

and the speed is

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

. Point B is

2.0\,\text{m}

above A and the speed there is the same. Calculate the gauge pressure at point B. (Take

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

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

)
