Where:

Q₁, Q₂, Q₃ – volume flows in (m³/s) or (m³/h),
ρ₁, ρ₂, ρ₃ – density in (kg/m³),
p₁, p₂, p₃ – pressure in (bar), recommended in (bar abs).

Indexs:

1 – transmission fluid at the entrance to ejector,
2 – suctioned fluid at the entrance to ejector,
3 – mixture of driving fluid and suctioned fluid on exit ejector.

When ordering ejektora should include the following information:

• Density in the ρ₁and  ρ₂ (kg/m³);
• Mass flows of m₁ and m₂ or at least one of them in kg/s or volume flows Q₁ and Q₂, or at least one of them in m³/s;
• Of the three pressure p₁, p₂ and p₃ the two must be given to the bar or bar abs_;
• If you were given all three of pressure it can be given only one mass or volume flow;
• Instead of mass flow rate can be set volume flows.
