Solve Problem 8.109a using the effectiveness-NTU method.

Data From Problem 8.109

(a) For the operating conditions prescribed in Problem  8.107 and a chip thermal conductivity of k_ch = 140 W/m · K, determine the water outlet temperature  and the chip power dissipation. Heat transfer from the sides of the chip to the surroundings and  from the side walls of a channel to the cap may be  neglected. Note that the spacing between channels, δ = S – W, is twice the spacing between the side wall of an outer channel and the outer surface of  the chip. The channel pitch is S = L/N, where  L = 10 mm is the chip width and N = 50 is the  number of channels.
