THE SCIENCE · model, equations & assumptionsApproximate model

The model solves a simplified operating point for a centrifugal pump, then advances the upper tank by conserving water volume. Flow is shown in L/s; calculations use SI units.

Pump curve: Hₚ = Hmax · n² − Kₚ · Q²
System curve: Hₛ = Hstatic + Kₛ · (Q/a)²
Q = √[(Hmax·n² − Hstatic) / (Kₚ + Kₛ/a²)]

Source: dVs/dt = R − Qpump
Tank: dVt/dt = Qpump − Qdemand − Qoverflow
dh/dt = (dVt/dt) / A
Hydraulic power: Pₕ = ρ g Q H
Electrical power: Pₑ = Pₕ / η

Units: Q in m³/s, H and h in m, A in m², volume in m³, power in W, energy in kWh, ρ = 1,000 kg/m³, g = 9.81 m/s².

Assumptions:

Constant cross-section, well-mixed upper tank and incompressible water.
The pipe resistance is approximate and proportional to f·L/D⁵; it is a lumped Darcy-inspired calibration.
Catchment recharge enters the lower source reservoir; demand is an imposed outflow.
The source-flow cap represents a simple intake constraint.
Weather, sky and particles are visual atmosphere, not a meteorological solver.

Honest simplifications: no water hammer, cavitation, air entrainment, temperature-dependent properties, detailed motor transients or real pump maps. Coefficients and events are illustrative, not engineering guidance. “Analytic” graph line assumes the current flow and demand remain constant from the starting level; it is a reference, not a forecast.
