Heat transfer correlation for a given convection situation was obtained as Nu = 0.5Re0.8 Pr0.4. Dry air passes over a similar object of 2 m characteristic length with a velocity of 10 m/s. What is the evaporation rate in unit area if at the liquid surface the mass concentration (the partial density of the liquid) is 0.00792 kg/m3? Physical properties; ν = 20x10-6 m2/s, Pr = 1, Le =1
A. 0.0025 kg/m2s
B. 0.31548 m/s
C. 0.31548 kg/m2s
D. 0.0025 m/s
