mass transfer

3.2 Text Problem 19.1-5. Here, I want you to calculate the mole loss (kgmol/s), at T=52.6C and P=1atm. There is a typo in the text; the Fuller equation is Eqn 18.2-9. 3.3 For the naphthalene sphere in the previous problem, how long would it take to completely evaporate at T= 52.6C and P=1atm ? a) Derive Text Equation 19.1-25 by recognizing that the rate of volume loss is proportional to the rate of molar flow, : You should get: b) Using MA=128.17kg/kgmol and A=1140kg/m, determine how long it would take a sphere of initial radius, r1=0.01m to evaporate.
