  • The rates of overall mass transfer of n-butyl acetate in the alkaline hydrolysis of n-butyl acetate were measured by using a mechanically agitated vessel in order to get the relationship between the mass transfer rates and experimental variables. The interfacial area between liquid-liquid heterogeneous phases could be obtained by comparing the theoretical values of reaction enhancement factor from an approximated solution of a diffusion equation based on the film theory with the experimental data.

  • As computation technologies has developed, the analysis using load transfer is mainly performed. But most of the functions used in the above program has been developed in foreign countries. Also in our nation, lots of studies concerning load transfer are being researched. The investigation of suitability about the piles installed in our grounds, however, is required as functions acquired experientially, basing on the piles installed in foreign grounds. In this background, the load transfer curve required to use load transfer method on its design through the analysis of field tests inside our nation intends to be made, on which this research focuses.
