    Natural Gas Pressure Increase with Elevation

    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...

    Natural Gas Pressure Increase with Elevation

    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...
