C_HQCurve {solaR}

H-Q curves of a centrifugal pump

Description

Compute and display the H-Q curves of a centrifugal pump fed working at several frequencies, and the iso-efficiency curve as a reference.

Usage

HQCurve(pump)

Arguments

pump

list containing the parameters of the pump to be simulated. It may be a row of pumpCoef.

Value

result

A data.frame with the result of the simulation. It contains several columns with values of manometric height (H), frequency (fe and fb), mechanical power (Pb), AC electrical power (Pm), DC electrical power (Pdc) and efficiency of the pump (etab) and motor (etam).

plot

The plot with several curves labelled with the correspondent frequencies, and the isoefficiency curve (named "ISO").
