By analyzing the engine's operating conditions and the cooling system's design, Rohan discovered that the radiator's airflow was restricted due to a faulty fan design. This reduced the convective heat transfer coefficient, leading to inadequate heat dissipation.

The team implemented Rohan's suggestions, and to their delight, the engine temperature dropped significantly. The "Speed Demon" was back on the track, competing fiercely and crossing the finish line with a happy and cool engine.

Using his knowledge of heat transfer modes (conduction, convection, and radiation), Rohan started to analyze the engine's cooling system. He realized that the radiator was not dissipating heat efficiently, leading to a buildup of heat in the engine.

Rohan, a recent graduate in mechanical engineering, had a strong foundation in thermal science and engineering. He had studied the principles of heat transfer, thermodynamics, and fluid mechanics from his favorite textbook, "Thermal Science and Engineering" by Mathur and Mehta.

And, as a bonus, Rohan found that the PDF of "Thermal Science and Engineering" by Mathur and Mehta was readily available online, a valuable resource that he would continue to refer to throughout his engineering career.

Armed with his analysis, Rohan proposed a solution to the racing team: redesign the fan to improve airflow and increase the convective heat transfer coefficient. He also recommended optimizing the radiator's tube layout to enhance heat transfer.
