FAQs

What is the formula for conductance of a pump? The conductance of a pump is typically not represented by a single formula. It depends on the specific design and characteristics of the pump. Conductance calculations for vacuum systems often consider the conductance of individual components in the system rather than the pump itself.

How do you calculate flow conductance? Flow conductance, often referred to as flow conductance (C) in vacuum systems, is calculated by taking the reciprocal of flow resistance (R). It can be expressed as C = 1/R.

What is the difference between conductance and pumping speed? Conductance measures the ease of gas flow through a component or system, typically expressed in L/s (liters per second). Pumping speed, on the other hand, measures the rate at which a vacuum pump can remove gas from a chamber or system, usually expressed in L/s or m³/s. Conductance is related to the characteristics of the components and their arrangement, while pumping speed is a property of the pump.
