Tip #9 Of Better Chemical Engineering: Calculation

I must say in my short time of being an engineer is that you need to be able to do quick calculations. And, by that I mean quick multiplications and back of the envelope calculations. These calculations will help show that you are smart and quick and can come to a conclusion quickly. Also you will always be able to back up any solutions you come to on the job with a quick calculation or some sort of similar derivation. Also being able to calculation rough derivations to prove you understand what is going on and what needs to be done to fix it. That is all. Know your calculations!
