25 cm² 45° 150 cm² 40 cm 3- A reducing elbow in a horizontal pipe is used to deflect water flow by an angle u = 45° from the flow direction while accelerating it. The elbow discharges water into the atmosphere. The cross-sectional area of the elbow is 150 cm2 at the inlet and 25 cm2 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 Water 30.0 kg/s momentumflux correction factor to be 1.03 at both the inlet and outlet. 4- Firefighters are holding a nozzle at the end of a hose while trying to extinguish a fire. If the nozzle exit diameter is 8 cm and the water flow rate is 12 m3/min, determine (a) the average water exit velocity and (b) the horizontal resistance force required of the firefighters to hold the nozzle. 12 m³/min

3- A reducing elbow in a horizontal pipe is used to
deflect water flow by an angle u = 45° from the flow
direction while accelerating it. The elbow discharges
water into the atmosphere. The cross-sectional area of
the elbow is 150 cm2 at the inlet and 25 cm2 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
Water
30.0 kg/s
momentumflux correction factor to be 1.03 at both the inlet and outlet.
