Today another update for Oil Calculator Pro (version 1.0.9) was released and is now available for download at Google Play:
After the release of version 1.0.8 we discovered some bugs during one of our bug testing sessions:
1: In the tables for LPG/NGL some combinations of temperature and density failed to achieve the correct CTL or reduced density. This has now been fixed with a slight amendment in rounding off rules inside the algorithms.
2: Rounding off in calculations for Metric tons in air / vacuum caused minor differences in the three decimals compared with other programs. This was also a rounding issue and has been resolved.
3: The viscosity/temperature conversion unit, which was added to the app in version 1.0.8 has now been expanded with a tool that utilizes the Walther equation and two sets of temperature and viscosity data. This is considerably more accurate than calculating an alternate viscosity or temperature based on one temperature/viscosity data pair only.
The viscosity / temperature tab now looks as can be seen in the following screenshot:
