3. A square isothermal chip is of width w = 0.5 cm on a side and is mounted in a substrate such that its side and back surfaces are well insulated; the front surface is exposed to the flow of a coolant at T=10C. From reliability considerations, the chip temperature must not exceed T= 250C. If the coolant is air and the corresponding convection coefficient is h = 50 W/mK, what is the maximum allowable chip power? (1 point) Plot the maximum allowable chip power with varying h (from 1 W/mK to 1000 W/mK). Use Matlab and attach your code for full credit. (2 points)
