Problem V: A reducing elbow in a horizontal pipe shown in Figure 5 is used to deflect the inlet and 25 cm2 at the exit. The density of water is 1000 kg/m³, and the flow rate of water flow by an angle 0 = 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 water is 0.03 m/s. 25 cm2 45° 150 cm2 Waters 0.03 m/s Figure 5 Question 21: What is the equation for the resultant force required to hold the pipe in position? (a) FR= FRx - FRy (b) FR= FRx + FRy V (c) FR=Fx- Fy (d) FR= Fx+ Fy (e) none of the above Question 22: What is the velocity of the water at the outlet? (а) 12m/s (b) 2m/s (c) 3.8m/s (d) 9m/s (e) 14.1m/s Question 23: What is the pressure at the inlet? (a) 56.2kPa (b) 70.0kPa (c) 35.5kPa (d) 14.7kPa (e) 18.0kPa
