Hydraulic & Pneumatic Calculator
AvailableAn open-source, 12-module calculator for hydraulic and pneumatic system design: from pump flow to cylinder force, from buckling to accumulators. Free and ad-free.

Piping, cylinder sizing, buckling, pump selection… it runs the calculations you constantly need in the field and at the project desk, in the browser and on the phone. The English edition is live at calculate.hidroteknik.com.tr, the Turkish one at hesapla.hidroteknik.com.tr, and the Android app is on Google Play.
Calculation modules: Hydraulic System Calculator (pressure, flow, power, cylinder force and speed), Advanced Hydraulic System (stage-by-stage pump, motor, and tank selection for multi-cylinder systems), Buckling & Rod Diameter (Euler, four end conditions), Gear Pump Selection Guide (picks from a real pump catalog), Pipe & Rod Weight, Pneumatic Cylinder, Hydraulic Motor, and Accumulator Sizing.
Workshop lifesavers are included too: Thread & Pitch Standards (Metric, BSP, NPT, UNF, UNC), Pipe Unit Converter (DN, inch, mm with a pipe table), Pressure Converter (bar, psi, MPa, kPa, atm, mmHg), and line sizing by recommended flow velocity.
The formulas behind the calculations are explained step by step in online guides. A single codebase compiles to both Android and the web; the source is open under the MIT license.
