Hot engine oil at 150°C is flowing in parallel over a flat plate at a velocity of 2 m/s. Surface temperature of the 0.5-mlong flat plate is constant at 50°C. Determine (a) the local convection heat transfer coefficient at 0.2 m from the leading edge and the average convection heat transfer coefficient, and (b) repeat part (a) using the Churchill and Ozoe (1973) relation.
