Pump Characteristic Curve

Pump Characteristic Curve

Pump characteristic curves are usually presented graphically describing the relationship between pump head, hp, and the flow rate, Q using either an exponential equation or 3-point quadratic form. The exponential pump characteristic curve is given as

where hc = the pump cutoff head … Read the rest

Inertia of Pumps and Motors from Innovyze H2OCalc – Idea for SWMM6

Inertia of Pumps and Motors

The combined inertia of pumps and motors driving them, including the connecting shafts and couplings, is required for transient analysis associated with the starting and stopping of pumps. The equations provided below are intended to be used as an initial guide to the inertia values … Read the rest
