Liquid mercury at 250°C is flowing with a velocity of 0.3 m/s in parallel over a 0.1-m-long flat plate where there is an unheated starting length of 5 cm. The heated section of the flat plate is maintained at a constant temperature of 50°C. Determine

(a) The local convection heat transfer coefficient at the trailing edge,

(b) The average convection heat transfer coefficient for the heated section,

(c) The rate of heat transfer per unit width for the heated section.
