Electrical motor nominal torque

Electrical motor nominal torque calculation based on motor nominal power and rotational speed.

Motor nominal torque

$$ T_n = {9550 \cdot \left({ {P_n \over n_n} }\right)} \; \; , Nm $$

Pipe friction head loss

Calculates head loss due to wall friction in pipelines using Darcy friction factor.

$$ Hf_{pipe} = {f_{Darcy} \cdot \left({ \left({ L_{pipe} \cdot V_{fluid} ^ 2 }\right) \over \left({ ID_{pipe} \cdot 2 \cdot g }\right) }\right)} \; \; , m $$

System curve factor

Determines relationship between flow and head loss in a pipeline

$$ k_{system} = {h_{loss} \over q ^ 2} \; \; $$
