question

A plate at 60°C, is cooled by forced convection from an airstream. The steady flow velocity of the air stream is observed to be 2m/sec with the temperature and pressure as 27°C and 1 atm., respectively. Find the heat transfer per unit width from the leading edge to a distance of (a) 20 cm, and (b) 40 cm. Also find (c) the drag force over the 40 cm distance.
