WattAFlow Water Turbine Calc

WattAFlow estimates the hydraulic power of a water turbine from the operating point and recommends a typical machine type from flow Q and head H – from Pelton, Francis and Kaplan to the hydropower screw. For a first layout of hydropower sites, teaching and quick what-if checks on the go. WHO IT’S FOR • Engineers, planners and operators in hydropower • Students and lecturers in turbomachinery and renewable energy HOW IT WORKS • Type volume flow Q in m³/s, head H in m and turbine efficiency η in % • Power updates as you type: P = ρ · g · Q · H · η with ρ = 1000 kg/m³ and g = 9.81 m/s² • Logarithmic sliders for Q and H, linear slider for efficiency • Type recommendation from flow and head, ranked by best suitability • Tap a recommended type for a short characterisation TURBINE TYPES • Pelton, Francis, Kaplan, cross-flow • Water wheel, hydropower screw, vortex turbine FEATURES • Live Q–H diagram with typical ranges and the current operating point • Copy the full result set to the clipboard • Precise numeric entry with a compact keypad in landscape • Light and dark themes (system / light / dark) • English and German interface • In-app help and legal notice UNITS • Volume flow: m³/s • Head: m • Efficiency: % (turbine, not generator) • Power: kW / MW PURCHASE Paid app: buy once, no ads, no in-app purchases. ACCURACY Type recommendations are based on typical application ranges. Suitability for a real plant must be checked with the turbine manufacturer. Developed by a project engineer with more than 15 years of experience in turbomachinery and thermodynamic cycles. Provided in good faith but without warranty of correctness or completeness.
