The leakage rate conversion with a calculation tool is a practical way of converting an existing value into different other units. The units can be changed using specific conversion factors (see below):
The definition of the leakage rate is necessary in order to make values comparable. The term leakage refers to the unintentional escape of gases or liquids from closed containers and pipework. There is no such thing as absolute tightness. It is therefore necessary to specify a permissible leakage rate in order to reduce the risk to people and the environment or to validate measurement results.
The leakage rate is the pressure multiplied by the volume flow rate per unit of time of a specific fluid through a leak under defined conditions in EN 1330. The flow rate of a fluid (liquid or gas) through a leak at a given temperature as a result of a specified pressure difference across the leak.
Other units for leakage rates are available in various regulations and standards. Conversions are possible (see above calculation programme for other conversions..
The unit of measurement for the leakage rate (qL) in the International System of Units (SI):
Pa•m3/s.
The conversions are only possible if the conditions are the same, e.g.
