Pipe Flow Calculations Forum

The capacity of a low pressure natural gas (less than 1 psi, 6.9 kPa) pipe line with a small pressure drop can be calculated with the Spitzglass formula q = 3550 k ( h / l SG)1/2 (1) where q = natural gas flow capacity (cfh) h = pressure drop (in Water Column) l = length of pipe (ft) k = [d5/(1 + 3....

It is a great work that you investigate the difference between the outflow (of a drainage system).

The pressure drop in saturated steam distribution pipes can be calculated in metric units as dp = 0.6753 106 q2 l (1 + 91.4/d) / ρ d5 where dp = pressure drop (Pa) q = steam flow rate (kg/h) l = length of pipe (m) d = pipe inside diameter (mm) ρ = steam density (kg/m3)

Thanks PipeFlowCalcs,
You gave this information is so excellent.

Thanks you share the air flow calculation method.

This is the natural gas pressure drop equation formula.

It is easy to install a fire pit instead of the BBQ,
