U$3\mathrm{.}736m^3{h}^{-1}$ of water is pumped through a plastic pipe with an inner diameter of $60mm$ from a street hydrant to the top of a $25m-$high building. The temperature is $25C$ The total length of the pipe is $160m.$ What will be the water pressure at the pipe outlet if the water pressure in the hydrant is $1\mathrm{.}6$MPa $?$ Neglect the resistances in the pipe.

Result: The pressure is $1\mathrm{.}08$MPa, the mean velocity in the pipe will be $3\mathrm{.}54m*s^{-1},$ and the coefficient of friction will be $0\mathrm{.}016.$
