Gas-main vs. Gas Rate Calculator & Guide Utilizzo e statistiche

The application allows the user to solve most of gas transportation problems, calculate the process of transporting natural gas (steam phase of LNG, LPG, associated petroleum gas, biogas) through a single-line pipeline. The graphical representation allows to instantly find the optimal solution and determine the influence of various factors on the gas transportation process. The application can help the user to get a calculation result that is sufficient for making an estimated engineering decision. Scope of application • Distribution and internal gas supply systems • Main-gas transport • Gas distribution and gas collection networks Key Features Using the application can be calculated: • gas flow rate in the pipeline for a given pressure drop and geometric characteristics of the pipeline • pressure drop in the gas pipeline (final or initial pressure) for a given flow rate and pressure drop • the length of the gas pipeline that provides a specified gas flow rate for a given pressure drop and diameter of the gas pipeline • the required diameter of the gas pipeline, which provides a specified gas flow rate for a given pressure drop and length of the gas pipeline • the blowdown time for stopped section of gas pipeline • the required power of the gas compressor, which provides the necessary degree of pressure increase for a specified natural gas flow rate. The compression process is adiabatic. The calculation can be performed for a single-or multi-stage compressor. The application uses: General Fundamental Isothermal Flow Equation (the basic equation of gas flow), American Gas Association Equation (AGA NB-13 method), Weymouth Isothermal Flow Equation, Panhandle A Isothermal Flow Equation. Panhandle B Isothermal Flow Equation, Institute of Gas Technology Isothermal Flow Equation. The user can choose one of them. The properties of the transported gas are determined on base of its composition. The user can select the gas composition from the previously entered ones, edit, add a new one, or delete the previously entered gas composition. The user can also select the pipe wall material and, accordingly, the absolute roughness value from the previously entered ones, edit, add a new value, or delete the previously entered material name and roughness value. For the convenience of calculations, the application provides a wide range of applicable units of measurement, as well as standard conditions for measuring gas flow. The accuracy of the calculation methods used in the application corresponds to or exceeds the accuracy of the methods for obtaining initial data available in engineering practice. The data entered by the user is saved and transferred between the calculation forms, which allows the user to quickly consider the problem of calculating the parameters of the gas pipeline from all sides. The results can be saved as a pdf file, as well as printed out. Terms of use: https://www.gas-main.info/#terms-of-use Privacy Policy: https://www.gas-main.info/#privacy-policy

Gas Rate Calculator & Guide

This is the feature packed Gas Rate Calculator & Guide, from Mr Combi Training! We've managed to cram all of this into one app.... • Metric and imperial gas rate calculators • Save, email or export your results to other apps such as Dropbox, Google Drive or Evernote • Built-in torch • Tightness and let-by timer • Conversion calculator • Full gas rate guide • Supports natural gas, butane and propane • Save manual calorific values for improved accuracy • Select between a 1 and 2 minute timer for metric meters • Selectable timer alert • Supports ¼ft³, ½ft³ 1ft³, 2ft³ and 5ft³ imperial test dials A guide has been built into the app with 6 pages: • Metric gas rate calculations • Imperial gas rate calculations • Heat input calculations • Let-by test procedure • Tightness test procedure • Permissible drops on the tightness test An extra Converter calculator is included in the app for simple conversions between gas rates and heat inputs. Simply select the type of gas, enter a value, select the units, press the 'Calculate' button and the calculator will show all gas rates (cubic metres per hour, cubic feet per hour and litres per second) and heat inputs (MJ/h, kW and BTUs per hour) based on the CV. The Tightness Testing function allows you to quickly select between the let-by and tightness tests and has an easy to use timer. No longer do you need to fiddle about with your phone's timer! Calorific values can be entered manually (and saved) for more accurate gas rate calculation results. The calorific value of natural gas in the UK varies from about 38.3 to 40.5 MJ per cubic metre; this can mean a difference in the gas rate calculation of more than 5%! With this calculator you can add the CV for your area in the settings page and avoid these inaccuracies. The default values set for butane and propane are both the same as supplied by Calor and BOC. The metric timer can be set to either 1 or 2 minutes. For U6 and G4 meters one minute is sufficient, for E6 meters two minutes is recommended for accuracy. The timer can be set to an audible alert, vibrate, both or neither. A torch function is included with this app if your device has an LED flash.
