The following data was used to study a packed bed. For the study, tests were run with the pellets (packing) saturated with water and hot air was blown through the bed to evaporate the water under adiabatic conditions. Effective particle diameter, dp=0.571 cm Packed Bed void fraction, = 0.75 Gas stream mass velocity, G = air*uave= 0.816 kg/m2s Temperature at particle surface, T=311 K Total system pressure, P = 9.77 x 104 Pa A. Calculate the gas film mass-transfer coefficient in a packed bed using 2 different correlations, one that includes the void fraction and one that does not. B. How do your answers in part A compare to the experiment value of kG=4.42 x 10-3 kgmole/m2s atm
