$2($a$)$ The Pitot$-$static tube shown here is typically

used in measuring fluid velocity. If this Pitot$-$static

tube is immersed in a fluid with upstream velocity,

$V$ and upstream static pressure, $P,$ develop an

equation to calculate the speed of the fluid system

in terms of the variables shown in the figure. $$ is the density of the fluid. The flow is incompressible,

inviscid and steady. State assumptions made.
