App Description
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
