Chemical Engineering

Bubble Point Pressure Calculator

Calculate the bubble point pressure of a binary liquid mixture using Raoult's Law. Use it when designing distillation columns or flash drums to determine when a liquid first begins to vaporize.

Chemical Engineering

Pipe Pressure Drop Calculator

Compute the friction term f·(L/D)·(v²/2) from the Darcy-Weisbach equation — the specific energy loss per unit mass of fluid flowing through a straight pipe. Multiply by fluid density to get pressure drop in Pa, or divide by g for head loss in metres.
