A computer cooled by a fan contains eight PCBs, each dissipating 10W power. The height of the PCBs is 12 cm and the length is 18 cm. The cooling air is supplied by a 25 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 10 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.

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
