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").
