Chemical Engineering AppSuite HD

March 7, 2015

This app has been updated by Apple to display the Apple Watch app icon. Although there has always been a really nice Periodic Table within the iPad version of the app, we've made it much easier to find and use as a PDF. Find it under 'General Info' -> 'Chemistry" on both the iPhone and iPad versions of the app. Fixed a bug that could cause the app to crash if the user entered invalid value in the Water Vapor Pressure or Air-Ideal Gas modules.

The long awaited next update to the ChemE App has arrived! Welcome to Version 3.0! Updated for iOS 8 with a new look and feel to app. A built-in calculator has been added to the iPhone version! This calculator not only does math, but can store and utilize variable names. Many more unit categories and unit types are available within the Converter. A greatly improved PDF viewer has been implemented for viewing 'General Info' files. Full-color PDF files for psychrometric charts, Friction Factors and Mollier diagrams have also been added. Thermophysical property model is now available for Carbon Dioxide under 'Water and Steam'. Expanded the Wilson VLE calculations to include over 675 pairs. Fixed bug in tank filling that incorrectly calculated values when filling/draining. Other bug fixes and performance enhancements.

Updates for both iPhone & iPad: New thermodynamic property calculators now available under 'Water and Steam': R-134a Ammonia Air (Ideal Gas) Added a Gas Constant Converter for rapid determination of 'R' in any units. Select mass/moles and PV/energy. A bunch of new tables and charts have been added PDFs to 'General Info'. All of these files can be exported via email and printed. A number of bug fixes, error corrections and other minor enhancements. iPad only: New 'Tank Filling' module in ChemE tools. We've built a lot of functionality into this feature. Check it out!

***Welcome to Chemical Engineering AppSuite 2.0!*** The app is now built for both iPhone and iPad and both versions will be updated simultaneously! The 2.0 release handles unit selection in an all new and intuitive way. The units are selected from easy to use scrolling views that are accessible directly from the equations. The built in converter has also greatly been expanded in the number of units available. New math tools - polynomial solver, interpolator New practice problem - learn chemical engineering fundamentals anytime from anywhere! More data now available for select compounds... heats of formation and combustion. Bug fixes and enhancements.
