Pipe Sizing For Self-Venting Flow

本帖最后由 chuanming 于 2014-3-29 10:13 编辑

针对Self-venting的管线尺寸选择,适用于精馏塔冷凝器下液管,精馏塔底部出液管等。

A properly designed drain line with gravity flow will be self-venting if the liquid Froude number (dimensionless parameter), is less than approximately 0.3

Fr = W/(g*D)^0.5 ≤ 0.3

Where g = 32.174 ft/s2 (9.8 m/s2) acceleration due to gravity
          D = inside pipe diameter, ft (m)
          W = velocity the liquid would have in the pipe flowing full with the given flow rate, ft/s (m/s)
