sci.pipe-network-Hardy-Cross Calculator
Solves pipe network flow distribution using the Hardy-Cross iterative method, balancing flows and heads at each node. Hardy-Cross converges in 5–10 iterations for simple networks — complex networks with many loops use the Newton-Raphson linearised method in EPANET hydraulic modelling software.
Inputs
Q Initial M3 S
Reference formula or conversion factor shown for context.
R Resistance
Opposition to current flow (Ω). V = IR. Resistors in series add; in parallel their reciprocals add.
N Exp
Reference formula or conversion factor shown for context.
Results
head loss hL (Pa)
The decrease or degradation from the baseline.
Hardy-Cross correction ΔQ (m³/s)
Sample size or count used in the calculation.
corrected flow Q + ΔQ (m³/s)
Reference formula or conversion factor shown for context.
