An electronic circuit board dissipating 50 W is sandwiched between two ducted, forced-air-cooled heat sinks. The sinks are 150 mm in length and have 20 rectangular passages 6 mm × 25 mm. Atmospheric air at a volumetric flow rate of 0.060 m3/s and 27°C is drawn through the sinks by a blower. Estimate the operating temperature of the board and the pressure drop across the sinks.
