Use the Compressor Discharge Temperature Calculator to estimate ideal adiabatic/polytropic discharge temperature. The calculator uses Inlet temperature, Inlet absolute pressure, Outlet absolute pressure, Heat capacity ratio / exponent and Efficiency and reports t2 estimate.
Read the result in the context of the selected units and pressure basis. For this tool, the primary outputs are t2 estimate. Change one input at a time when comparing scenarios so the effect of each variable remains clear.
PneumaForge applies this verified method: Ideal: T2s=T1·r^((k-1)/k). Optional estimated actual discharge temperature: T2≈T1+(T2s-T1)/η_T when user supplies a temperature/isentropic efficiency assumption. The functional engine is shared with related tools in the compressor-thermo family, while this page solves the specific intent represented by compressor discharge temperature calculator.
Ideal: T2s=T1·r^((k-1)/k). Optional estimated actual discharge temperature: T2≈T1+(T2s-T1)/η_T when user supplies a temperature/isentropic efficiency assumption.Reproducible example: start with the calculator's default values (Inlet temperature = 20; Inlet absolute pressure = 1.01325; Outlet absolute pressure = 8.01325; Heat capacity ratio / exponent = 1.4) and calculate the result. Then change the variable most relevant to your application and compare the new t2 estimate against the baseline.

It is designed to estimate ideal adiabatic/polytropic discharge temperature. The reported outputs are t2 estimate.
The calculator uses Inlet temperature, Inlet absolute pressure, Outlet absolute pressure, Heat capacity ratio / exponent and Efficiency. Only use values that represent the same operating condition or design case.
The calculation follows: Ideal: T2s=T1·r^((k-1)/k). Optional estimated actual discharge temperature: T2≈T1+(T2s-T1)/η_T when user supplies a temperature/isentropic efficiency assumption. The page also states the assumptions that define where the method is valid.

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.
