Acomputer cooled by a fan contains eight pcbs, each dissipating 9w power. the height of the pcbs is 11 cm and the length is 18.8 cm. the cooling air is supplied by a 20 w fan mounted at the inlet. if the temperature rise of air as it flows through the case of the computer is not to exceed 9 c, determine (a) the flow rate of the air that the fan needs to deliver and (b) the fraction of the temperature rise of air that is due to the heat generated by the fan and its motor.
