on the pipes, such as: Complementary modules of calculations are incorporated in the program, The downstream pressure in a houseline after the meter/regulator is in general in the range of 7 to 11 inches Water Column, or about 1/4 psi. Specific gravity of natural gas is set to 0.60. piping. Only emails and answers are saved in our archive. This Pipe Pressure Drop Calculation Excel Sheet is specially designed by a professional engineer and pipe pressure drop calculation expert to calculate pressure drop in a pipe system. Liquid Pressure Drop in Pipe and Pipe Fittings Spreadsheet Calculator. Please read AddThis Privacy for more information.

The Darcy Weisbach equation [ hL = f (L/D)(V2/2g) ] gives a relationship among pipe length and diameter (L and D); average velocity in the pipe (V); frictional head loss (hL); and friction factor (f), where the friction factor is, in general, a function of Reynolds number (Re) an… resulting end pressure is high enough to satisfy the requirements of the next piece of equipment, should not be interpreted as an absolute criteria, to guess pipe ID until it met end pressure criteria, calculated flow rate is the same as target flow rate, Cooling Tower Makeup Water Calculation with Example, Sizing of Compressor and Instrument Air Capacity, How to Calculate Jockey Pump Capacity in Fire Fighting System, Sizing of Expansion Tank for Hot Oil System, Several Natural Gas Dehydration Methods and Range of Application, Qu’est-ce que le traitement des eaux usées – yourshopping.fr, The Difference between Pre-feasibility Study and Feasibility Study, Inert Gas Purging Requirement Calculation, How to Write Marketing Aspect of Feasibility Study, Typical Configuration of Pump in Piping and Instrumentation Diagram (P&ID), How To Estimate Optimum Insulation Thickness, Sizing and Horse Power Estimation of Counterflow Induced-Draft Cooling Tower, Hydrate Prediction using Vapor-Solid Equilibrium Constant, How to Calculate NSPH of Pump with Examples and Illustrations, Understanding Flammability Limit and Explosive Limit. of generators of heat.
All the results above are got from this spreadsheet. done, that is to say: All the cells of calculation in purple are programmed. Saturated Properties Calculator watch tutorial view guide Calculates saturated liquid and gas properties for a given pressure or temperature using the IAPWS Industrial Formulation 1997. pressure drop along the pipe run; the actual pressure drop is found by dividing the figure in column 7 by the figure in column 8. But, I tried again and yesterday I got a satisfied results. The nearest value is 2.47 in (NPS 2.5 in). Congratulations everyone. Last time I put wrong data for gas specific gravity at standard condition, so that the results is different from I got from simulator. Edited by Yasserkassem, 30 October 2019 - 07:54 AM. Parameters required for this template are allowable pipe diameter, pipe roughness, pipe length, pipe flow rate, fluid density, and fluid viscosity. This calculation program on Excel makes it possible to dimension and carry out the calculation of the pressure losses on the distribution systems of combustible gas use such as for example for the gas feeding of generators of heat. particularly holds account operating conditions and specific characteristics
I can’t donwload it, Hi Dede, you can download the spreadsheet via the link at the end of the post.
Make Shortcut to this Calculator on Your Home Screen? study: For each sheet of the table of calculation, the presentation is The pressure drop is 1.595 psi. Gas pressure drop calculation Based on API RP 14E, single-phase gas lines should be sized so that the resulting end pressure is high enough to satisfy the requirements of the next piece of equipment.
In this post, I want to share you how to do natural gas line sizing (actually the method is applicable for all kind of gases). I usually use process simulator when it came to natural gas line sizing. I hope you find it useful. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! start from the same file, to insert a new worksheet or to duplicate The velocity is also a noise problem if it exceeds 60 ft/s.
By using second equation, I guessed value of pipe ID (d, in inch) so that I have calculated flow rate is the same as target flow rate, which is 0.4008 MMscfd. macro-commands. and carry out the calculation of the pressure losses on the distribution Then we got : This is a spreadsheet I used to calculate line size of gas manually. But the result is not the same as from simulator. I used Norsok to determine the value of acceptable P2. d = inside diameter pipe (in) Natural gas line sizing calculated in this post will be from manual calculation and from process simulator. the phase calculation. Liquid pressure drop- oil pressure drop calculation Two phase flow - AGA equation, Liquid hydrostatic head calculation, Tank hydrostatic head calculations, Liquid and gas retention time in separators, Pressure drop using Hazen–Williams equation, Calculation of Viscosity of crude oil and emulsion and different temperature, Three phase separator calculation (sizing) -Different method, Three phase separator calculation (sizing), Heat required for heating crude oil and emulsion, GPSA -Gas Processing Suppliers Association, Different methods to calculate gas pressure drops in pipes, or gas rate in case of know pressure drop and piping data, Gas properties at different temperature and pressure, Mass flow to volumetic flow and vice versa, Pipe capacity - pipe weight - pipe contradiction, Liquid and gas - simple - rule of thumps, Two phase flow pressure drop - API equation, Liquid pressure drop- oil pressure drop calculation, Cdu Overhead Neutraliser Dosage Calculations, This is not recommended for shared computers.
