Consider Problem 3.144a.
(a) Using an appropriate correlation from Chapter 8, determine the air inlet velocity for each channel in the heat sink. Assume laminar flow and evaluate air properties at T = 300 K.
(b) Accounting for the increase in air temperature as it flows through the heat sink, determine the chip power qc and the outlet temperature of the air exiting each channel. Assume the airflow along the outer surfaces provides a similar cooling effect as airflow in the channels.

Data From Problem 3.144a

(a) Consider limitations for which the array has  N = 11 fins, in which case values of the fin thickness  t = 0.182 mm and pitch S = 1.982 mm are obtained  from the requirements that W = (N – 1)S + t and  S – t = 1.8 mm. If the maximum allowable chip  temperature is T_c = 85°C, what is the corresponding  value of the chip power q_c? An adiabatic fin tip condition  may be assumed, and airflow along the outer  surfaces of the heat sink may be assumed to provide a convection coefficient equivalent to that associated with airflow through the channels.
