Gas flow calculation through orifice
WebCalculation of natural gas pressure drop is also available as incompressible flow. Calculator p1 - absolute pressure on the start of pipe line [bar]; p2 - absolute pressure on the end of pipe line [bar]; Sg - relative density [ - ]; L - pipe length [km]; qh - volumetric flow rate [m3/h]; D - internal pipe diameter [mm] ; WebIf you neglect viscosity, Bernoulli's equation (just Navier-Stokes without frictional or stress terms) will get you into the ballpark: P g + 1 2 ρ g v g 2 = P a. Where the g subscripts pertain to the gas and the a subscript to the ambient. The gas density ρ g ≡ M / V is the ratio of the mass of gas (M) in the tank to the volume of the tank ...
