Dear forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

Static Pressure (SP) + Velocity Pressure (VP) = Total Pressure (TP)
SP is related to Velocity (V) through VP. V=4005 * sq rt of(VP/density factor(df)), where df typically = 1 for simple systems (unless you need to account for temperature, moisture, elevation, and absolute pressure which all together could account for a total of 20% variation in this factor).
