Coefficients of centrifugal pumps.

Coefficients of centrifugal pumps

data(pumpCoef)

A data frame with 13 columns:

Qn: rated flux
stages: number of stages
Qmax: maximum flux
Pmn: rated motor power
a, b, c: Coefficients of the equation H=a \cdot f^2+b \cdot f \cdot Q+c \cdot Q^2.
g, h, i: Coefficients of the efficiency curve of the motor (50 Hz): \eta_{m}=g \cdot (\%P_{mn})^2+h \cdot (\%P{mn})+i.
j, k, l: Coefficients of the efficiency curve of the pump (50 Hz): \eta_{b}=j \cdot Q^2+k \cdot Q+l.

With this version only pumps from the manufacturer Grundfos are included.
