WebThe Froude number criterion mentioned in the standard NORSOK P-001 (2006) appears to apply for draining from a process vessel. A Froude number less than 0.3 is recommended to ensure the vertical pipe is running full. If the Froude number is increased beyond 0.3, a weir is formed at the top surface and air is sucked into the liquid flow. WebNov 9, 2009 · Simpson identified a maximum upper value of 0.3 for the Froude number for reliable self-venting flow through a nozzle entering a vertical pipe [Perry’s Chemical Engineers’ Handbook, 8th ed., p. 6-29 (2008)]. This means the outlet nozzle will run less than half full at the nozzle entrance and gives the design equations: blue chip growth portfolio guggenheim
