m A fluid flows at 0.001 - through a 100- mm diameter pipe. Determine whether the flow is laminar or turbulent if the fluid is • a) hydrogen (v = 1.08 x 10¬4 m² /s b) air (v = 1.51 x 10-5 m² /s) c) gasoline (v = 4.06 x 10-7 m²/s) d) water (v = 1.02 x 10-6 m² /s) E) mercury (v = 1.15 x 10-7 m² /s %3D

Use four decimal places in all solution

1) A manometer is attached to two pipes as shown. If knowing mercury SG is 13.6, sea water SG is 1.035, and fresh water p is 1,000 kg/m³, determine the pressure difference between two pipelines at the centers. Fresh Water h. -60 cm Air hair -70 cm hea <- 40 cm Mercury Sea Water hi -10 cm

2. The total flow from A to E is 300 L/s. Compute the flow for pipes 2, 3, 4, and 5 3 5 D 6 Pipe 1 2 3 4 5 6 f 0.02 0.02 0.02 0.02 0.02 0.02 Diameter Length (mm) in (m) 450 400 250 360 200 600 300 1400 250 450 300 700
