A horizontal $100-mm$ diameter pipe $(f=0\mathrm{.}027)$ projects into

a body of water $1$ m below the surface $($Fig$.$ x$8\mathrm{.}27\mathrm{.}3).$

Considering all losses, find the pressure at a point $5$ m from

the end of the pipe if the velocity is $4\frac{m}{s}$ and the flow is $($a$)$

into the body of water; $($b$)$ out of the body of water. no there are Kentry or Kexit
