Hydraulic pressure-drop power
Inputs
User-entered pressure loss across the stated bounded circuit element or aggregate; no network is solved.
User-entered flow through the stated pressure-drop record; duty, leakage, and flow distribution are not derived.
Percent greater than 0 through 100 used to report a literal time-scaled loss-power average.

Method
Formula, when it applies, and when it does not
Convert pressure drop and flow into hydraulic loss power, then scale it by an active-time fraction without sizing a circuit or thermal system.
Ploss = Δp·Q/600; Pavg = Ploss·D/100; Eper elapsed hour = Pavg·1 h
When
- Declared pressure drop and flow
- Metric hydraulic power conversion
- Scalar time-average arithmetic
Don’t
- This multiplies only a declared pressure drop by a declared flow, then scales the result by a declared active-time fraction. It does not select a pump, valve, hose, reservoir, accumulator, cooler, or component; infer system efficiency; model networks, temperature, fluid properties, accumulators, heat rejection, duty cycles beyond the stated scalar fraction, capacity, safety, suitability, or approval.
