Water from a large tank is discharged into atmosphere through a pipe of varying cross sectional area. If the pipe

outlet area is $0\mathrm{.}3$m$2$ and the volume flow rate is $5$m$3$

$/$s$,$ calculate the head of water in the tank above the pipe

outlet. From this, calculate the static pressure at a section of the pipe of area $0\mathrm{.}45$m$2$ whose elevation is $6$m

above the pipe outlet.
