$6-25$ A reducing elbow is used to deflect water flow at a

rate of $30$kg$/$s in a horizontal pipe upward by an angle theta $=45$ from the flow direction while accelerating it$.$ The

elbow discharges water into the atmosphere. The cross$-$

sectional area of the elbow is $150$cm$^(2)$ at the inlet and $25$cm$^(2)$

at the exit. The elevation difference between the centers of

the exit and the inlet is $40$ cm $.$ The mass of the elbow and the

water in it is $50$ kg $.$ Determine the anchoring force needed to

hold the elbow in place. Take the momentum$-$flux correction

factor to be $1\mathrm{.}03.$
