eng.pipe-network-Hardy-Cross Calculator
Solves a pipe network for flow distribution and head losses using the Hardy Cross iterative method. Hardy Cross iteration adjusts flow in each loop until head loss balance is achieved — modern networks use linear theory or Newton-Raphson, but Hardy Cross is the classic manual method.
Inputs
Q Initial M3S
Reference formula or conversion factor shown for context.
K Resistance
Opposition to current flow (Ω). V = IR. Resistors in series add; in parallel their reciprocals add.
Head Loss Minor M
Reference formula or conversion factor shown for context.
Iterations
Reference formula or conversion factor shown for context.
Results
corrected pipe flow (m³/s)
Reference formula or conversion factor shown for context.
head loss in pipe (m)
The decrease or degradation from the baseline.
ΔQ correction per iteration = -Σh_f/(2Σ|K·Q|)
The proportional relationship between two quantities.
