Relationship between gas flow rate and pressure
Thread Content
Gas flow rate has nothing to do with pressure; why is the flow rate higher at higher pressures
In a closed pipe, the pressure is the same everywhere; no flow rate can occur even if the pressure is high. A large difference in pressure between one end and the other results in a high flow rate
The principle of air flow is the same as that of direct current. Ohm’s law states that current = voltage/resistance; a similar theory is also applied to gas flow. Pressure and voltage seem to have similar properties. The concept of voltage actually refers to potential difference; potential difference/resistance = current. When applied to gases, it becomes pressure difference/pipeline resistance = gas flow rate. The gas flow rate is directly proportional to the pressure difference between the two ends of a pipe (P1-P2) and inversely proportional to the resistance of that pipe
There is still a certain relationship; for example, under the same pressure difference but different pressures, a higher pressure results in a larger flow rate.
Is there pressure compensation? The traffic is generally displayed in nominal terms.

Pressure affects flow velocity; higher pressure means a higher flow velocity. If the cross-sectional area remains constant, a higher flow velocity results in an increased flow rate.
