Air at 45C flows parallel to a 25cm by 20cm square plate made of naphtnalene. The superficial velocity of the air is 0.5m/s flowing parallel
Air at 45C flows parallel to a 25cm by 20cm square plate made of naphtnalene. The superficial velocity of the air is 0.5m/s flowing parallel to the longer side. The diffusivity of naphthene in air at 45C is 6.92106m2/s and the vapor pressure of solid naphthalene is 0.555mmHg. a. Calculate the mass transfer coefficient using: i. Reynolds Analogy ii. Taylor-Prandtl Analogy iii. Von Karman Analogy iv. Chilton-Colburn J-Factor Analogy v. Correlations b. Using the mass transfer coefficient from correlations, determine the sublimation rate of naphthalene from the plate. Air at 45C flows parallel to a 25cm by 20cm square plate made of naphtnalene.
