Reconsider example problem 12-2, using the correlations of C. Chavarie and J. R. Grace [Ind. Engrg Chem. Fundamentals, Vol. 14. No. 2 pp. 75-79 & 86-91 (1975)]

(a) Calculate the average bed porosity, bubble diameter, frequency of bubble rise, and velocity of bubble rise,
(b) Conversion
(c) Compare the results with those given in the example problem, Calculate the conversion using the Orcutt, DPPF and DPPM models.
(d) What is the effect on conversion if the particle size is increased by a factor of 5 for each of the limit situations discussed in section 12-6?
