1 Loss coefficient or also pressure loss coefficient, pres-
sure loss coefficient, drag coefficient is denominated
with factor here.
2 The mass flow rate indicates the mass of a medium that
moves through a cross section within a period of time.
The mass flow rate is also referred to as flow rate. As a
standard, it can be calculated with 1.0 here.
3 Air is the carrier gas.
Under standard conditions (temperature 20 °C and air
pressure 1013 mbar) the density of air is ~1.2 kg/m³.
4 The kinematic viscosity describes the relationship be-
tween dynamic viscosity and consistency.
Under standard conditions it is always 0.000015 m³/s.
