Pressure Drop Equation For Gas. Pressure drop for gas flow General equation The general equation for calculating gas flow is stated as (Eq 11) where Assumptions no work performed steadystate flow and f = constant as a function of the length Simplified equation For practical pipeline purposes Eq 11 can be simplified to (Eq 12) where.
PDF fileThe Ergun4 equation generally accepted as descriptive of the pressure drop of a single phase fluid flowing through a fixed bed is for the gas A&Z =fe [Cl W3] p&Id (6) The main difference between Equations (5) and (6) is the exponent on the porosity term.

The friction factor f from Eq (44) is f = (1 − 033 0333)[175 + 150 ( 1 − 033) 135] = 464 The pressure drop – Δ Pt is − ΔP t = fρv2sL gcDp N / m 2 − ΔP t = 46409487 × 14752 × 25 1 × 0003 = 79 809N / m 2 = 0798bar McDonald et al equation a = 18 b = 180 f = 502 and −Δ Pt = 86368 N/m 2 = 0864 bar.
Compressible gas flow
= Pressure Drop (kg/m 2) = Resistance Coefficient (determined by test or vendor specification) p = Density (kg/m 3) ω = Flow Velocity Pressure drop by gravity or vertical elevation Where Δp = Pressure Drop (kg/m 2) p = Density (kg/m 3) g = Acceleration of Gravity (98 m/s/s) ΔH = Vertical Elevation or Drop (m) Pressure drop of gasses and vapor.
Calculator: Pressure Loss through Piping for Gas TLV A
Gas is propane Required flow is 120 cfh at 30″ wc pressure drop Per equation 2b Q 2 = 120 x √ (1/30) = 22 cfh From Figure 1 C d for 15° convergent nozzle is 094 so corrected flow is 22/094 = 234 cfh Locate 234 cfh in the propane column of the orifice table and then read to the left to find a #26 drill size orifice.

Gas velocity = 3318 ft/s End pressure = 4327 psia or pressure drop = 043 psi (use equation 1) By using process simulator we got Gas velocity = 3418 ft/s End pressure = 4328 psia or pressure drop = 0426 psi The result is similar too BONUS! This is a spreadsheet I used to calculate line size of gas manually.
