Consider atmospheric air at u? = 2 m/s and t? = 300 k in parallel flow over an isothermal flat plate of length
l = 1 m and temperature ts = 350 k.

(a) compute the local convection coefficient at the leading and trailing edges of the hot plate with and without an unheated starting length of ? = 1 m.

(b) compute the average convection coefficient for the plate for the same conditions as part (a).

(c) plot the variation of the local convection coefficient over the plate with and without an unheated starting length.
