At a certain point in a horizontal pipeline, the water's speed is $6\mathrm{.}0\frac{m}{s}$ and the gauge pressure is $1\mathrm{.}80{10}^{4}Pa.$ Find the gauge pressure at a second point in the line if the crosssectional area at the second point is $3\mathrm{.}0$ times that at the first?

a$)2\mathrm{.}03{10}^{5}Pa,$

b$)2\mathrm{.}26{10}^{5}Pa,$

c$)2\mathrm{.}91{10}^{4}Pa,$

d$)2\mathrm{.}85{10}^{4}Pa,$

e$)3\mathrm{.}40{10}^{4}Pa.$
