Dry air enters an inclined pipeline in the upward direction being preheated. The pipe has an inner diameter of 0.3 m and a total length of 5 m with a 30° inclination from the horizontal direction. The air enters at 300 kPa (absolute) with a velocity at 3 m/s, density of 3 kg/m³, and at an ambient temperature of 20°C. The electrical heaters around the pipe surface provides a uniform heating flux of 2 kW/m² and the exiting pressure was measured to be 150 kPa. Assume ideal gas behavior, and the air specific heat can be approximated as Cp= = 900+ 0.37 (where T is in Kelvin). Please calculate the exiting temperature of the air.
