Pump hydraulic power
Water or another liquid, steady flow. Pipe losses are not calculated here — put the head you already have.
Method
P = ρgQH. Worked case: 0.02 m³/s, 15 m, water, 70% gives 2.94 kW hydraulic and 4.20 kW shaft.
Not a system curve, NPSH check or manufacturer selection.
Logic: how this figure is built.
