$6-25$ A reducing elbow in a horizontal pipe is used to deflect water flow by an angle $=45$ from the flow direction while accelerating it$.$ The elbow discharges water into the atmosphere. The cross$-$sectional area of the elbow is $150c{m}^2$ at the inlet and $25c{m}^2$ 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 momentumflux correction factor to be $1\mathrm{.}03$ at both the inlet and outlet.
