HydraCal: Professional Hydraulic Engineering Tool

Perform complex hydraulic calculations in seconds with HydraCal. Designed for mechanical engineers, technicians, and system designers, this app provides accurate results for hydraulic cylinders, accumulators, pumps, motors, and piping systems without needing an internet connection.

Key Features:

✅ HydraCal Cylinder Calculator: Calculate Forces (Push/Pull), Speeds, Stroke Times, Volumes, and Flow Rates. Supports Regenerative Mode calculations and analyzes return flow ratios.

✅ Electric Motor Sizing: Determine the required motor power (kW / HP) based on flow and pressure. Includes efficiency factors and standard IEC/NEMA motor size recommendations.

✅ Accumulator Sizing: Don't guess the capacity. Calculate the exact accumulator volume and pre-charge nitrogen pressure (P0) required for your system efficiently. Supports both Isothermal and Adiabatic cycles.

✅ Piping & Flow Analysis: Calculate oil velocity and Reynolds Number to determine flow type (Laminar vs. Turbulent). Includes pressure drop estimations based on fluid viscosity.

✅ Free Fall & Decompression:

Free Fall Analysis: Evaluate if a load will fall freely by balancing gravity, friction, and back pressure forces.

Decompression Shock: Calculate the compressed oil volume and safe decompression time to prevent hydraulic shock (water hammer).

✅ Engineering Reference Guide: A built-in digital handbook containing formulas, constants, and diagrams for Pumps, Motors, Cylinders, and Fluid mechanics.

✅ Unit Converter (Metric & Imperial): Seamlessly switch between Metric (mm, bar, kg, L/min) and Imperial (inch, psi, lbs, GPM) units. Perfect for global projects.

✅ Ad-Free Experience: No ads, no distractions. A clean, professional interface focused purely on engineering productivity.
