Coefficients of centrifugal pumps.

Description

Coefficients of centrifugal pumps

Usage

data(pumpCoef)

Format

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.

Details

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