Procedures (cont.)

• The shaft work of the compressor is equal to the difference of enthalpy before and after the compressor.

• The same amount of shaft work is produced across the turbine section as assumed.

• In order to determine the temperature entering the turbine (T4), we need to find the temperature exiting the turbine (T5) and it is related to the temperature exiting the nozzle (T6) as it is expanding in the nozzle through an isentropic process.
