Question:
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 kch = 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.
