A water pipe ascends a $30\mathrm{.}0$ m vertical height. The pipe is $4\mathrm{.}0$ cm in diameter. If the velocity of the water is constant throughout, how does the pressure of the water at the bottom of the pipe compare to the water pressure at the top?

Select answer from the options below

Pbottom $=$ Ptop $+2\mathrm{.}9$ x $105$ Pa $$

Pbottom $=2\mathrm{.}9$ Ptop $$

Pbottom $=$ Ptop $-2\mathrm{.}9$ x $105$ Pa $$

Pbottom $=$ Ptop $+1\mathrm{.}0$ x $105$ Pa $$

Ptop $=2\mathrm{.}9$ Pbottom $$
