Tabulated pump (TL)#

simplified version of centrifugal pump without reference data and shaft angular velocity

The block describes the operation of the pump according to a given Q-H characteristic.

Pump pressure increment is described by the formula (1):

(1)#\[\Delta P=\Delta H_{ref}(q)\cdot \rho \cdot g\]

where:

\(\Delta H_{ref}(q)\) - pressure characteristic is determined by linear interpolation by vectors of volumetric flow rate and head, [m];

\(\rho\) - fluid density, [kg/m\(^3\)];

g - free fall acceleration, [m/s\(^2\)].

Volumetric flow rate is defined as (2):

(2)#\[q=\frac{\dot{m}}{\rho}\]

where \(\dot{m}\) - mass flow rate of liquid, [kg/s].

Law of conservation of energy (3):

(3)#\[\phi_A+\phi_B+P_{hydro}=0\]

where \(P_{hydro}\)=\(\Delta p \cdot \frac{\dot{m}}{\rho}\)
