Abstract
Forty assorted Allihn and Graham condensing models were studied to investigate their performance on extraction of natural dye, solvent recovery and simple distillation of borehole water. AutoCAD was used to design the models with introduction of bulbs at the outer jacket ranging from one to ten bulbs and fabricated using borosilicate glass tubes. Hypothesis was formulated as Ho (null hypothesis) and HA(alternate hypothesis) to test the results obtained from the characterization of modified Allihn and Graham condensing models which was subjected under statistical analysis using t-test and analysis of variance (ANOVA) to ascertain the efficacy of condensing models. All the statistical analysis revealed that the alternate hypothesis results finding is accepted by ANOVA only on extraction. However, the null hypothesis is retained by either of analysis of variance or t-test on solvent recovery and simple distillation.
