A piece of electrical equipment is cooled by a labyrinth of 1.0-cm ID water tubes made of 12 straight sections, each 80 cm long joined at ends by 90° connectors and 12-cm straight bridging pieces. The cooling water enters the labyrinth from a large header and discharges to another large header such that the velocity at both ends is negligible. If the water velocity is 1.5 m/s, determine the pressure drop and heat removal capacity of the labyrinth with 40°C water temperature rise.
