Use the Compressed Air Nozzle Consumption Calculator to estimate free-air use of an air nozzle from orifice and pressure. The calculator uses Orifice/nozzle diameter, Upstream absolute pressure, Downstream absolute pressure, Air temperature and Discharge coefficient Cd and reports air consumption.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are air consumption. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Compressible orifice/nozzle flow. The functional engine is shared with related tools in the compressible-orifice family, while this page solves the specific intent represented by air nozzle consumption calculator.
Compressible orifice/nozzle flowReproducible example: start with the calculator's default values (Orifice/nozzle diameter = 2; Upstream absolute pressure = 7.01325; Downstream absolute pressure = 1.01325; Air temperature = 20) and calculate the result. Then change the variable most relevant to your application and compare the new air consumption against the baseline.

It is designed to estimate free-air use of an air nozzle from orifice and pressure. The reported outputs are air consumption.
The calculator uses Orifice/nozzle diameter, Upstream absolute pressure, Downstream absolute pressure, Air temperature and Discharge coefficient Cd. Only use values that represent the same operating condition or design case.
The calculation follows: Compressible orifice/nozzle flow. The page also states the assumptions that define where the method is valid.
Ideal-gas, quasi-steady, known discharge coefficient C_d. P₁,P₂ absolute. Flag non-air gases unless γ,R supplied.
Yes. PneumaForge converts supported units through canonical engineering units. For compressed-air reference flows and pressure bases, the reference pressure and temperature must also remain consistent.
