Still calculating pressure drop in pipes with pen, paper, and calculator… and worrying if you made a small mistake?

You’re not alone. Every mechanical engineer has felt this pain.

Whether it’s Darcy–Weisbach equation, friction factor confusion, or unit mismatch—pressure drop calculations can quickly become time-consuming and error-prone, especially during design reviews or site work.

That’s why I built a simple tool that does the hard work for you 👇

Pressure Drop in Pipe Calculator

Just enter:

* Pipe length

* Diameter

* Fluid density

* Velocity

* Friction factor

And get accurate pressure drop instantly⚙️
