On basis of ISO-Standard 2314, the German Standard Organisation (DIN) has prepared the German Standard DIN 4341, which deals with acceptance tests for gas turbines. Sample calculations have been included.

In connection with the development of the sample calculations a new diagram for thermodynamic properties of air and products of combustion was developed on basis of

-humid air as per ISO standard 2314

-standard gaseous fuel

-standard liquid fuel

This diagram allows exact calculation of performance data.

Further, a simplified but relatively acurate formula is presented for calculating the turbine inlet temperature on basis of

-compressor pressure ratio

-exhaust gas temperature

-thermal efficiency

Development and limitation of this formula is presented.
