The Natural Gas Properties app calculates thermodynamic and calorific properties of Natural Gas mixtures.
Calculated Properties:
- Molar Weight
- Specific Gravity
- Compressibility Factor
- Heat Capacity
- Thermal Conductivity
- Dynamic Viscosity
- Mass/Mole/Volumetric Lower/Higher Heating Values
- Wobbe Index
- Motor Octane Number (MON)
- Methane Number (MN)
- Hydrocarbon Dew Point @ P
- Hydrocarbon Dew Point @ 1 atm
- Water Dew Point @ P
- Water Dew Point @ 1 atm
- Water Content in ppmv
Basis:
Compressibility Factor, Density and Dew Points are calculated with the Peng-Robinson Equation of State (PR EOS). Heating Values are calculated according to Brazilian Standard NBR 15213 (Calculation of calorific values, density, relative density and Wobbe index of combustible gases from composition), which is equivalent to the ISO Standard 6976:1995 (Natural gas - calculation of calorific values, density, relative density and Wobbe index from composition).
Input Options:
Input options include mole and mass fractions/percentages, temperature and pressure.
Supported Systems of Units: SI, CGS and Imperial (English).
Output Options:
- Table view
- Shareable text report

A wonderful app, except you can’t export the data. If you try to send it somewhere (text, email, etc.) it crashes and you’ll have to re-enter everything. If you try the other option of saving the txt file, it gets saved in a location inaccessible without jailbreaking.
The only options are to copy 3+ screens of data by hand or take 4 photos with your phone and emailing the photos to your desktop.
My system is an iPad Pro 6th gen running iPadOS 16.5.1. Same problem running on an iPad Pro 10.5 inch with 15.5.1.
The share text feature does work on an iphone12 running 16.5.1
