Hydraulics and Waterworks lite

About this app

he Hydraulics Calculator offers 94 calculators to simplify your hydraulics, waterworks, and civil engineering calculations — available in both Metric (SI) and Imperial (USCS) units. Explore core calculators for free, with the option to unlock the complete Hydraulics Calculator suite through a simple one-time purchase. Key Features: Smart auto-fill pickers for pipe materials, fluid properties, channel linings, soil types, pipe fittings, orifice/weir coefficients and runoff coefficients Flow regime indicators — Froude number (Subcritical/Critical/Supercritical) and Reynolds number (Laminar/Transitional/Turbulent) Hydraulic jump classification Built-in reference tables for all material and fluid properties General Hydraulics * Capillary Rise * Viscosity / Kinematic Viscosity * Hydrostatic Pressure * Pressure Head / Velocity Head / True Velocity Head * Specific Energy Head / Head Loss (Bernoulli Equation) * Total Energy (Elemental Volume of Fluid) * Total Head of Flowing Fluid * Average Velocity of Flow * Summation of Forces (X direction) Dimensionless Numbers * Froude Number * Reynolds Number * Weber Number Friction Losses * Head Loss due to Friction (General / Darcy-Weisbach) * Chezy Velocity / Chezy Coefficient * Manning Flow Velocity (including pipe diameter) * Flow Rate, Head Loss, and Pipe Diameter (Manning) * Hazen-Williams Flow Velocity and Friction Loss Pipe Flow and Fittings * Head Loss across Pipe Diameter Changes * Brightmore Equation for Pipe Contractions * Head Loss from Pipe Fittings * Loss Coefficient Orifice and Fluid Flow * Orifice Flow Rate / Coefficient of Contraction * Initial Velocity of Fluid Jets * Gage Pressure in Conical Tubes * Wave Velocity in Pipes (Water Hammer) * Pipe Material Stress * Section Factor Hydraulic Jumps * Force, Momentum Change, and Head Loss Temperature Effects on Pipes * Stress and Length Movement due to Temperature Culverts and Channels * Elevation Differences (Headwater and Tailwater) * Velocity and Flow Rates in Culverts * Open Channel Flow — Rectangular, Triangular, Parabolic, and Trapezoidal Channels Circular Channels * Cross-Sectional Area, Critical Depth, Top Width, and Flow Rate Weirs * Flow Rate — Rectangular, Triangular, Trapezoidal, and Broad Crested Weirs Sediment and Water Movement * Sediment Transport (Schoklitsch Formula) * Evaporation Rate (Meyer Equation) * Wind Factor Rainfall and Groundwater * Peak Discharge (Rational Formula) * Rainfall Intensity (Steel Formula) * Groundwater Flow (Darcy’s Law) Specialized Calculations * Fire Demand Rate * Gravity and Artesian Well Flow Rates * Economic Pipe Diameter * Venturi Flow Meter * Power from Water Flow
