Air velocity Flow Charts Table

[EMS21]

Hi
I'm looking for a website or something like a spread sheet for the "Air velocity Flow Charts" so I can create a Lookup Table for a Pitot tube reading.
I would have thought NIST would have had this info handy but nothing turns up.

TIA
Thomas

No need for a lookup. Velocity is directly calculatable from velocity pressure.

I'm looking for an excel type of format to create a scaling file or a lookup table, the "scaling file" is the best to work with. I can enter that Equation from Dwyer but there is also a limited number of Calculated Parameters as these are used for other parameters in the DAQ software. I could put something together in Excel a slower approach with limited skills in excel.

Thanks again
Thomas

Vlookup table will not work as well as entering the formula. Just enter the in. wg velocity pressure reading & calculate FPM velocity = (in wg velocity pressure)^.5 x 4005 in another cell. The 2nd cell should use the valu of in. wg velocity pressure in the first cell.

Vlookup tables are discrete, not exact and continuous as the formula.
