Consider an ideal brayton cycle for a jet engine consisting of a compressor, combustion chamber, turbine and nozzle. the pressure and temperature entering the compressor are 105 pa and 300 k respectively. the pressure ratio across the compressor is 6 to 1, the temperature at the turbine inlet is 1000 k, and the pressure at the nozzle exit is 105 pa. assume that cp remains constant through the engine at a value of 1000 j/kgk and  = 1.4. calculate temperature at the exit of the compressor.

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
