Calculation of the volume of the instrument air buffer tank
Thread Content
According to HG/t20510-2014, the formula for calculating the volume of an instrument air buffer tank is V = 60qV1 tP. /(P1 – P2), qV1 – the designed gas supply capacity of the gas supply unit, in Nm3/h; P1 – the normal operating pressure, in kPa(A); P2 – the minimum delivery pressure, in kPa(A); P0. One atmosphere of pressure, usually ρ. = 10 1. 33kPa(A); t – holding time, in minutes. According to the old standards and practical meaning, the formula in the new specifications is incorrect; it should be V = qV1 tP. /60 (P1 - P2)
You’re absolutely right; the standards are the latest ones, but the experts really don’t conduct any reviews.
It’s probably a problem caused by formatting; the original poster did a very thorough investigation. Like it!
1. Master physics well – in that way, you can derive almost all engineering data on your own, and calculate the optimal values as well as the appropriate ranges. 2. Experts are too busy to spend time figuring out calculation formulas. :lol.

Those who write standards are generally not rigorous scientists or anything extraordinary; they’re probably just ordinary people who copy nine sentences for every sentence they modify. It’s normal for them to make mistakes when copying, modifying, or calculating.
