Consider the chip on the circuit board of problem 639 to, Ask an Expert

Engineering

Consider the chip on the circuit board of Problem 6.39. To ensure reliable operation over extended periods, the chip temperature should not exceed 85°C. Assuming the availability of forced air at T_∞ = 25 C and applicability of the prescribed heat transfer correlation, compute and plot the maximum allowable chip power dissipation P_c as a function of air velocity for 1 ≤ V ≤ 25 m/s. If the chip surface has an emissivity of 0.80 and the board is mounted in a large enclosure whose walls are at 25°C, what is the effect of radiation on the P_c- V plot?
