If you love gadgets, try building a to experiment with the concepts from Chapter 7:
Heat‑and‑mass‑transfer engineering is often thought of as a “lab‑coat” discipline, but its principles are woven into the fabric of modern life. Chapter 7 of (Cengel, 5th ed.) focuses on heat exchangers , a technology that quietly powers many of the comforts, conveniences, and sources of fun we enjoy daily.
This is where the math gets tricky. The chapter provides numerous equations (correlations) to calculate the Nusselt number based on the geometry.
$$Q = h A (T_s - T_\infty)$$ $$A = 2 \text m \times 1 \text m = 2 \text m^2$$ $$Q = (12.83 \text W/m^2\cdot\textK) (2 \text m^2) (80 - 20)^\circ \textC$$ $$Q \approx 1540 \text W$$
