Assignment Help Electrical Engineering
Reference no: EM13879912

A printed circuit board (PCB) is cooled by laminar, fully developed air flow in adjoining, parallel-plate channels of length L and separation distance a. The channels may be assumed to be of infinite extent in the transverse direction. and the upper and lower surfaces are insulated. The temperature T, of the PCB board is uniform, and air flow with an inlet temperature of Tm,i is driven by a pressure difference, ?p.
