Question 1: Pipe Flow (find head loss) Water flows steadily within a pipe at constant density p = 999.1 kg/m. Three locations are marked on the pipe. Location 1 is at the beginning of the straight pipe segment, location 2 is at the end of the straight pipe segment or the beginning of the elbow, and location 3 is at the end of the elbow. The straight pipe segment has: inner diameter: D = 0.05 m length: L = 1.72 m friction factor: f = 0.07. The elbow inside the CV has: inner diameter: D = 0.05 m (same as straight pipe segment) height: H = 0.28 m loss coefficient: KL = 0.7. Z A1 P L g A2 P2 ' P3 A3 H Velocities are approximately uniform over A1, A2, and A3. If the flow is Q = 0.015 m/s, calculate h23, the head loss due to friction between locations 2 and 3. hL23= number (rtol=0.02, atol=1e-08) m
