A10 stage axial flow compressor develops an overall pressure ratio of 8.0 with and isentropic efficiency of 0.85. the absolute velocity component of air enters the rotor at an angle of 27â° to the axial direction. the axial component of velocity is constant throughout the compressor and is equal to 150 m/s. if the ambient air conditions are 15â°c and 1 bar, determine the angle which the relative component of velocity makes with the axial direction at the exit of the rotor.

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
