HYDRAULIC ENGINEER is the most comprehensive hydraulic engineering calculator
available on the App Store, featuring over 1,000 formulas across 13
specialized calculator categories, 8 temperature scale converters, and 8
professional reference tables.
CALCULATOR CATEGORIES
- Actuator Formulas — cylinder force, stroke, speed, and rod calculations
- Fluid Power — pressure, flow, horsepower, and torque calculations
- Pump Laws — affinity laws for speed, flow, pressure, and power
- Vehicle Drive — drive speed, tractive effort, gradeability, and drawbar pull
- Hydraulic Tubing — wall thickness, burst pressure, and working pressure
- Cylinder Calculations — extend/retract speed, rod end area, and cycle times
- Thermal Hydraulics — heat generation, reservoir cooling, heat exchangers,
and energy to heat fluid
- Oil Velocity & Pressure Loss — pipe velocity, pressure drop per foot, and
total system losses
- Pipe Flow — Reynolds number, Darcy-Weisbach head loss, laminar friction, and
orifice flow
- Accumulator Sizing — discharge volume, precharge pressure, adiabatic and
isothermal gas volumes
- Reservoir Sizing — open/closed circuit sizing, cylinder-based sizing, and
oil weight calculations
- AC/DC Electrical — Ohm's law, power, resistance, inductance, and motor
selection
- Area Formulas — 60 geometric area calculations for every common shape
700+ CONVERSION FORMULAS
Pressure, horsepower, BTU, flow rates, linear measure, square measure, cubic
measure, liquid measure, weights, watts, power, HVAC, metric, sand-to-volume,
and fraction conversions.
8 TEMPERATURE SCALES
Convert between Celsius, Fahrenheit, Kelvin, Rankine, Reaumur, Newton,
Delisle, and Romer — 56 conversion formulas covering every combination.
8 PROFESSIONAL REFERENCE TABLES
- Pipe Schedule (Schedule 40 & 80)
- ISO Viscosity Grades
- Recommended Flow Velocities
- Hydraulic Hose Sizing (SAE)
- JIC Thread Sizes
- Pipe Roughness Values
- O-Ring Sizes (AS568)
- Wire Rope Working Load Limits
KEY FEATURES
- Save and share any calculation result
- Share reference tables
- Calculation history
- Favorites for quick access to your most-used formulas
- Switch between US Customary and SI Metric units
- Dual-unit display shows both US and metric values simultaneously
- Dark mode optimized interface
- Works offline — no internet connection required
PREMIUM UPGRADE
Unlock sharing, advanced calculator sections, and unlimited history with a
one-time lifetime purchase — no subscriptions.
HYDRAULIC ENGINEER is designed for working hydraulic engineers, technicians,
maintenance professionals, and engineering students. If there are formulas or
reference tables you'd like to see added, just use the built-in feedback
feature to let us know.
