Re: max flowrate for natural gas
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....

Re: exit flow under water/in open air
It is a great work that you investigate the difference between the outflow (of a drainage system).

Re: how to calculate steam flow
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)

Re: Natural Gas pipe pressure loss w/input 56''w.c.
This is the natural gas pressure drop equation formula.

Re: Gas fire pit sizing for existing gas line
It is easy to install a fire pit instead of the BBQ,
