At the start of cruise the temperature and pressure of the air entering the engine may be taken to be 259 .5K and 46.0 kPa. Assume a pressure ratio of 1.6 for flow through the fan which enters the core and a pressure ratio of 25 in the core compressor itself. Assume isentropic efficiencies of 90% in each component. Find the temperature rise across the fan of the flow entering the core compressor, the temperature entering the core compressor and thence the temperature at exit from the core compressor.

Transcribed Image Text:At the start of cruise the temperature and pressure of the air entering the engine may be taken to
be 259 .5K and 46.0 kPa. Assume a pressure ratio of 1.6 for flow through the fan which enters the core
and a pressure ratio of 25 in the core compressor itself. Assume isentropic efficiencies of 90% in each
component. Find the temperature rise across the fan of the flow entering the core compressor, the
temperature entering the core compressor and thence the temperature at exit from the core
compressor.
