IV$)$ A closed vessel maintains a pressure of $30g.$ The vessel discharges into a $4-$ft diameter

pipe and at the end it discharges to atmosphere. Flow velocity through the pipe is $20fps.$ If the

head loss is $8ft,$ calculate the pressure $($psi$)$ in the pipe at point $A$

$($A$)90$

$($B$)68$

$($C$)39$

$($D$)19$
