Determination of flow-rate characteristics

How to test flow rate characteristics

: Values which divide the passing mass flow rate of an equipment in a choked flow condition by the

: It is the pressure ratio which will turn to the choke flow (downstream pressure/upstream pressure)

: It is the flow in which the upstream pressure is higher than the downstream pressure and where

: Flow greater than the critical pressure ratio

: Air in a temperature state of 20°C, absolute pressure 0.1 MPa (= 100 kPa = 1 bar), relative humidity

product of the upstream absolute pressure and the density in the standard condition.

when it is smaller than this values. (critical pressure ratio)

sonic speed in a certain part of an equipment is reached.

Gaseous mass flow rate is in proportion to the upstream pressure and not dependent on the

downstream pressure. (choked flow)

65%.

It is stipulated by adding the abbreviation (ANR) after the unit depicting air volume.
