Conductance

Conductance

1.2.8 Conductance. Generally speaking, vacuum chambers are connected to a vacuum pump via piping. Flow resistance occurs as a result of external friction between gas molecules and the wall surface and internal friction between the gas molecules themselves (viscosity).

Types of flow

Types of flow

In the range between 2,300 < Re < 4,000, the flow is predominantly turbulent. Laminar flow is also possible, however, both types of flow being unstable in this range. Turbulent flow in a vacuum only occurs during pump-down operations from atmospheric pressure or when rapid venting is carried out.
