The formula to calculate the Nusselt Number (N) is:
\[ N = \frac{h \times L}{k} \]
Where:
The Nusselt Number is a dimensionless quantity used in fluid dynamics and heat transfer to analyze the convective heat transfer between a solid surface and a fluid. It represents the ratio of the convective heat transfer to the conductive heat transfer across a boundary layer. By calculating the Nusselt Number, engineers can optimize the design of systems to enhance heat transfer and improve overall energy efficiency.
Let's say the convective heat transfer coefficient (h) is 50 W/(m²·K), the characteristic length (L) is 0.5 meters, and the thermal conductivity (k) is 0.6 W/(m·K). Using the formula:
\[ N = \frac{50 \times 0.5}{0.6} \approx 41.67 \]
So, the Nusselt Number (N) is approximately 41.67.
