# Pipe Flow Gas Pressure Drop Calculator App

## Calculate Gas Pressure Drop

The Pipe Flow Gas Pressure Drop App calculates the pressure drop for gas flow in a pipe. Friction losses are calculated using specialist compressible isothermal flow equations (including the General Fundamental Flow equation, Complete Isothermal Flow equation, AGA Flow equation, Weymouth Flow equation, Panhandle A Flow equation, Panhandle B Flow equation, and the IGT Flow equation). The pressure drop in the pipe is affected by items such as the internal roughness of the pipe material, internal pipe diameter, length of pipe, gas flow rate, pressure at the start of the pipe, and gas density at the entry condition.Users can select items from from the pipe database, fitting database, and fluid database, and this data can then be used in the calculation.

## Gas Pressure Drop Calculation Results

Tapping "Calculate Pressure Drop" calculates the total pressure loss for the specified gas flow rate (in mass flow, standard flow volume, or compressed flow volume at the entry pressure). The individual pressure losses for each item are displayed on the results screen.## Share Calculations

Calculations can easily be saved to your device or shared with other users of Pipe Flow Gas Pressure Drop. The App can also generate professional PDF / Excel Reports that can be sent via email and viewed on any device.## Choose Isothermal Gas Flow Equation & Compressibility Model

Users can select which compressible isothermal equation is used in the gas calculations:

The software defaults to a standard atmospheric pressure of 1.01325 bar, however this can be modified by the user as required.

A range of standard volume units for gas flow rate are available within the software. The user can select their required reference condition from one of the following standard conditions:

- General Fundamental Isothermal Flow
- Complete Isothermal Flow
- AGA Isothermal Flow
- Weymouth Isothermal Flow
- Panhandle A Isothermal Flow
- Pandandle B Isothermal Flow
- IGT Isothermal Flow

The software defaults to a standard atmospheric pressure of 1.01325 bar, however this can be modified by the user as required.
