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.

According to problem -
Air pressure = P=1 atm
Inlet air temperature
= t =100 oc
T =273 +100 =373 ok
R = universal gas constant =0.082 atm-liter /mol – ok
Length 0f naphthalene flat plate = L = 1 m =100 cm
Distance of boundary layer edge = d = x = 0.5 m = 0.5*100 = 50 cm
Physical properties of Naphthalene
Molecular wt = C10H8 = 128 g /mole
Density at 100 oc = ρ= 0.9625 g /cm3
Boiling point - 218 o c
Melting point = 80.3 o c
Vapour pressure = 2.5 Kpa at 100 o c
Viscosity = μ = 0.761...
