How to choose the pipe diameter? ?
Thread Content
If the medium in my pipeline currently consists of both a liquid phase and a vapor phase, how should I choose the pipe diameter?
The pipe diameter is determined based on flow rate in the same way
Reply to 2# superkiller0305: It’s certainly necessary to determine the pipe diameter based on the flow rate, as there are recommended flow speeds for both liquids and gases to ensure that the pressure drop doesn’t become too high. What I’m not clear about now is how I should choose a reasonable flow rate in this situation If I calculate using the total mass flow rate and average density, the average density will be very low due to the presence of gas in the medium, which results in an overestimated volume flow rate. Could this lead me to choose a pipe diameter that is too large?
Reply to 3# plf2830: For calculations related to gas-liquid two-phase flow, you can refer to \"Design and Installation of Process Piping in Petrochemical Industries\" or other manuals, which provide information on how to calculate the average flow velocity of two-phase flow.
