Air is compressed in an adiabatic compressor. Inlet and outlet conditions are 120kPa, 30 oC and 20 m/s; 1.4 MPa, 530 oC and 80 m/s. The surrounding air temperature is 25 oC. The inlet cross-sectional area is 0.013 m2. Assume Cp = 1005 J/kgK, R = 287 J/kgK, k = 1.4. Enter the amount of heat loss due to irreversibility resulting from the heat transfer from the compressor in kW (correct up to one decimal place.)

Air at a static temperature and pressure of 8°C and 75 kPa respectively enters the intake of an aircraft gas turbine engine with a velocity of 196 m/s. The intake may be regarded as a diffuser with an inlet area of 0.4 m2 and an exit area that reduces the air flow velocity essentially to zero. Calculate the mass flow rate (kg/s) of air through the intake, given the specific gas (air) constant as 287 J/(kg.K), keeping three decimal places.
