Question $1$

As shown in the figure, the top view of the elbow and nozzle with water flow through has a gauge pressure of $150$kPa at section $(1)$ and flow rate $Q=0\mathrm{.}14\frac{m^3}{s}.$ Assume the flow is frictionless and irrotational. Note that water at section $(2)$ is NOT discharge to the atmosphere $)(0.$ Calculate:

$($a$)$ the gage pressure at section $(2),p_2.$

$($b$)$ the magnitude and direction of the anchoring force needed to hold the horizontal elbow and nozzle in place.

Answer:

$F=9080\mathrm{.}258$ N$,$
