Question:
A heat exchanger for heating liquid mercury is under development. The exchanger is visualized as a 15-cm-long and 0.3-m-wide flat plate. The plate is maintained at 70°C, and the mercury flows parallel to the short side at 15°C with a velocity of 0.3 m/s.
(a) Find the local friction coefficient at the midpoint of the plate and the total drag force on the plate.
(b) Determine the temperature of the mercury at a point 10 cm from the leading edge and 1.25 mm from the surface of the plate.
(c) Calculate the Nusselt number at the end of the plate.
