Forced air at 25C and 10 m/s is used to cool elec-tronic
Chapter 7, Problem 7.38(choose chapter or problem)
Forced air at 25?C and 10 m/s is used to cool elec-tronic elements mounted on a circuit board. Consider a chip of length 4 mm and width 4 mm located120 mm from the leading edge. Because the boardsurface is irregular, the flow is disturbed and theappropriate convection correlation is of the formNux?0.04Rex0.85Pr0.33.Estimate the surface temperature of the chip, Ts, if itsheat dissipation rate is 30 mW.
