Helpful online Calculators for solving for Pipes - V, Q, and rectangles.

Helpful online Calculators for solving for Pipes - V, Q, and rectangles.

(OP)
I asked in a previous thread http://www.eng-tips.com/viewthread.cfm?qid=307866 and found some calculators online to do what I was looking for. I mainly wanted something that I could plug and chug on my phone while at a meeting, without reinventing the wheel.

The first solves what I wanted for Q or V based on pipe diameter.

The second solves for a circle equivalent to a rectangle pipe.
