This need a lot of work. I suspect that no one that speaks English is editing this program. Virtually unusable. ### 1/5 — Dr *2011-05-20* A mix of basic stuff and formulae of dubious origin. Poor documentation for basis. ### 2/5 — Dissappointed *2010-08-27* This is not worth $5. They published the app before completing all the formulas. This should be a free app until it has the formulations installed. ### 1/5 — Rubbish app *2010-03-26* This is a rubbish app. You'll be wasting your money. Rubbish app. ### 1/5 — Of limited use *2010-03-19* Imperial units only, and no information on formulae used. ### 2/5 — Units aren't explicit *2010-03-11* It has potential, but it was a premature release. There are imputs that don't explicitly show you the units. Although you can figure it out by variable constriant. It was definently put together by an engineer, functionality over aesthetics. It is more geared toward a environmental engineer rather than a process engineer. If you are a ChE student, probably should shop some more. although I would keep my eye on it, for he may update this program. ### 2/5 — Process Engineer *2010-02-19* Chemical Engineering is wide I understand but nothing on pumps, pressure drop or heat exchangers? ## Frequently asked questions about Chemical Engineering Formulate ### What is Chemical Engineering Formulate?
