Air at 1 atm and 100°C flows across a thin, flat plate of naphthalene that is 1 m long, causing the plate to sublime. The Reynolds number at the trailing edge of the plate is at the upper limit for a laminar boundary layer. Estimate:
(a) The average rate of sublimation in kmol/s-m2
(b) The local rate of sublimation at a distance of 0.5 m from the leading edge of the plate
Physical properties are given in Example 3.14.
