Alph Version 1.4

With the release of Version 1.4 of Alph, a fluid property and process calculator for the Apple iPad, iPhone and iPod Touch, users can easily copy and paste variables and modeling tools and build sub-flowsheets within the tool. The program enables calculations related to heat exchanger balances, stoichiometric reactions, polytropic compressors, single or multiple material recycle processes, and refrigeration processes. The new copy-and-paste capabilities let users create their own library of frequently used calculations, which they can then paste into new studies, as needed. Other time-saving features allow users to create new objects exactly where they want them on the information flow diagram (rather than having to move them later). On the iPad, users can also automatically append object names to formulas by simply tapping on the appropriate object icon on the background diagram. This reduces typing and the potential for spelling errors. All objects can also have comprehensive notes attached to them to support related calculations.
