Turbine Selection by Head and Flow

Head–Flow Screening Chart

Log–log chart of net head against flow per unit, with Pelton, Francis and Kaplan screening regions and constant-power contours. Your project operating point is marked. Regions are general screening guidance — not absolute turbine limits or manufacturer envelopes.

Your project pointDashed grey lines: constant net electrical power (η ≈ 0.86) — 100 / 500 / 1,000 / 5,000 / 30,000 kW

Turbine Selection Assistant

Step-By-Step Screening

Add project constraints to the head and flow data. The assistant lists candidate turbine types, the reasoning, and the further engineering checks required.

Required plant output (kW)

Grid frequency

Flow-duration / seasonal variation

Sediment concentration

Space / shaft-arrangement constraint

Complete the constraints and run the evaluation to see candidate turbine types, rationale and required engineering checks.
