Thanks for the quick reply LittleInch
I worked out the pressure correction using:
h = K x (1-G) x H
where,
K = 0.123 (dimensionless)
h = pressure change due to altitude (mbar)
H = altitude change (metres)
G = density of the gas relative to air (dimensionless)
Is this the correct formula and...
Hello,
There are 2 points on a gas network with a height difference of 103metres - I have worked out that the elevation correction should be around 2.5mBar between the points. My question is, does it make a difference if the pressure in the pipe at these points is at a high or low pressure...
