Problem 10
The properties of air at 30°C are read as ρ = 1.165 kg/m3, kinematic viscosity = 16.0×10–6 m2/s, diffusion coefficient D = 2.6 × 10–6 m 2 /s, Sc = v/D = 0.615. The density of water vapour at 30°C = 1/32.9 kg/m3 , the density of water vapour in dry air is zero.
Problem 11
Assume turbulent flow from the leading edge. D = 1.2 × 10–9 m2/s, density of water = 1000 kg/m3, kinematic viscosity = 1.006 × 10–6 m2 /s, Sc = 1.0006 × 10–6 /1.2 × 10–9 = 838.33.
