Appendix E – Problem 1

E.1 What is the velocity required in a 300 mm diameter pipeline with a downward slope of 20° to prevent any small air bubbles from moving in the direction opposite the flow direction?

Solution:

Use Eq. E.2 to compute the minimum velocity V_m required for hydraulic transport of non-dissolved air with a = 0.2148, b = 0.3716, D = 0.3, and θ = 20°.

V_m = 1.12 m/s
