Airflow (velocity of u∞=15m/s, the temperature of T∞= 15°C) sweep over a flat surface with an area of 0.25 m2 and a temperature of 140 °C. The airflow induces a drag force of 0.25 N on the surface. What is the heat transfer rate across the surface? You can use Table A.4 in the lecture slides or other available data to evaluate air properties (Hint: Use Modified Reynolds analogy) (10 points)
