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. You may need the following formula: The formula for the roots of a general quadratic equation ax² + bx+c = 0 is -b ± √b²-4ac 2a

4. Jack, an engineering student, is taking in the great view while he was on the ship's deck, but as he is enjoying the cold wind tickling his face, he noticed that there is an iceberg about to hit the ship, but instead of reporting it, his curiosity took the best out of him, he hurriedly went to his backpack and took his notebook and pen out. He wondered how big the iceberg is underneath and how much of it is above the seawater. By observing, he calculated that the density of the ice is pice = 2013 Ibm/m² and floats in seawater, and by analyzing the saltiness of the water that hits his face he learned that the density of the seawater is psw = 1213 kg/m?. (2.25lbm = 1.20kg) a. What fraction of the iceberg is beneath the surface of the water? b. What fraction of the iceberg is above the surface of the water? c. Should Jack ask for Rose's help in the upcoming midterm exam?
