Hydraulic Engineer Calculators is a practical hydraulic engineering calculator and formula app for engineers, technicians, students, contractors, operators, and anyone working with fluid flow, pipes, pumps, pressure, open channels, hydraulic cylinders, or fluid mechanics. Quickly enter your values, select units, calculate an estimate, review result details, and check the formula used. Hydraulic calculators included: Flow & Pipe Calculators - Pipe Flow Velocity - Calculate fluid velocity from flow rate and pipe diameter - Flow Rate - Calculate volumetric flow from flow area and average velocity - Required Pipe Diameter - Estimate pipe diameter from design flow and velocity - Reynolds Number - Calculate Reynolds number for internal fluid flow Head Loss Calculators - Darcy-Weisbach Head Loss - Estimate pipe friction head loss - Hazen-Williams Head Loss - Estimate water pipe friction loss - Minor Loss - Calculate losses from fittings, valves, entrances, exits, and components Pressure & Head Calculators - Pressure to Head - Convert pressure to hydraulic head - Head to Pressure - Convert hydraulic head to pressure - Hydrostatic Pressure - Calculate pressure caused by fluid depth - Bernoulli Total Head - Calculate total hydraulic head Pump Calculators - Pump Power - Estimate hydraulic pump power from flow, head, and efficiency - Pump Head from Pressure - Calculate pump head from pressure difference - NPSH Available - Estimate Net Positive Suction Head Available Open Channel Flow Calculators - Manning Rectangular Channel - Estimate rectangular channel flow - Froude Number - Calculate the Froude number - Critical Depth - Estimate critical water depth - Orifice Flow - Calculate fluid discharge through an orifice Hydraulic System Calculators - Water Hammer Pressure - Estimate pressure rise from a rapid velocity change - Hydraulic Cylinder Force - Calculate cylinder force from pressure and piston area - Hydraulic Cylinder Speed - Calculate piston speed from flow rate and bore diameter Fluid Properties Calculator - Specific Gravity - Calculate specific gravity from fluid density Useful for: - Hydraulic engineering - Fluid mechanics - Pipe flow and pipe sizing - Water flow and pressure - Head loss and pipe friction - Pump systems and pump power - NPSH calculations - Open channel flow - Hydraulic cylinders - Water hammer - Irrigation, plumbing, water, and wastewater systems - Civil and mechanical engineering Supported units include: - m, mm, cm, ft, in - m², cm², mm², ft², in² - m³/s, m³/h, L/s, L/min, US gpm, ft³/s - Pa, kPa, MPa, bar, psi - m/s, ft/s - W, kW, hp Built-in formula guide Each calculator includes its formula, and the app links to a Hydraulic Engineer Guide with additional information about formulas, variables, units, calculation steps, practical uses, and important considerations. Selected calculators also include dynamic diagrams to help visualize values used in pipe, pressure, head, open channel, tank, and hydraulic cylinder calculations. Simple workflow: - Choose a calculator - Enter your known values - Select units - Tap Calculate - Review the result and details - Check the formula - Open the related guide for more information The built-in search makes it easy to find a specific hydraulic calculator by category or name. Important disclaimer These calculators provide preliminary hydraulic estimates only. Results are not a substitute for professional engineering judgment, certified calculations, manufacturer specifications, site-specific analysis, or applicable codes and standards. Always verify input values, units, fluid properties, pipe specifications, equipment limitations, safety factors, operating conditions, site conditions, and governing requirements before using a calculation for design, procurement, installation, testing, operation, maintenance, or any safety-critical application.
