HGT 20510-2014: Issues with formulas in the design specifications for instrument air supply
Thread Content
In the HGT 20510-2014 Standard for the Design of Instrument Air Supply, the formula used to determine the volume of the air storage tank is V=60 qv1 t P0 /(P1-P2). Shouldn’t it be V= qv1 t P0 /(P1-P2)/60? There is a difference of 60*60=3600 times between the two, which is a significant difference! ! !
It seems there is indeed a problem here
Upon consulting the drafting team, a corrigendum was issued later to correct the formula to V= qv1 t P0 /(P1-P2)/60
The calculation formula in the specification is incorrect; your understanding is correct.

The standard specifications are way too casual. Furthermore, using qv1 in the calculation formula is also incorrect; qv2 should be used instead
