Chapter 2, Problem 2.46(choose chapter or problem)
A fan forces air over a computer circuit board with a surface area of \(70 \mathrm{~cm}^{2}\) to avoid overheating. The air temperature is 300 K while the circuit board surface temperature is 340 K. Using data from Table 2.1, determine the largest and smallest heat transfer rates, in W, that might be encountered for this forced convection.
