Correction Factor for Gas Flow When Gas is Under Pressure

A Mazzei venturi is commonly used to inject/dissolve ozone gas into water and is an excellent tool for this job.  Mazzei provides excellent performance charts illustrating the precise ozone gas suction the Venturi will create based on water flows and pressures through the Venturi.  However, the venturi can also be used with a pressurized ozone gas line, essentially, when ozone gas is under pressure at the “suction” port of the venturi.  When used in this fashion the flow-rate of gas into the water stream will be higher.  This can be calculated as shows below:

 

 

 

 

 

 

 

 

SCC = Suction Capacity Correction

GP = Gas Pressure

This calculation provides a correction factor that can be used to multiply the listed gas flow rate on the Mazzei Venturi performance chart.

Example:

Gas Pressure (GP) of 10 PSI:

Pressurized Gas Source Calculated

 

 

 

 

 

 

 

 

The correction factor based on this example is 2.82

Listed suction (from performance chart) of 2.5 SCFH:

 

Suction caluclated

In this example, 7.05 SCFH is our expected ozone/oxygen gas flow into the venturi.

 

Note:

At very high gas flow rates, water pressures in the piping at the discharge of the venturi will increase due to the increase volume of water + gas in the piping.  This may change the variables used to calculate the expected gas flow rate and final flow-rate of gas into water. High gas flows may also alter the head-loss of gasses in the ozone/oxygen tubing and alter the actual gas pressure at the suction port of the Venturi.
