Specific Heats

Values for the heat capacities of ice and resulting water from initial temperatures of between 0 °C. and − 78.5 °C. to a final temperature of + 25.00 °C. are measured to ± 0.05% or better with an improved adiabatic calorimeter previously described. The specific heats of ice over the temperature range 0° C. to − 80 °C. are found and the latent heat of fusion of ice at 0 °C. is obtained from these heat capacity determinations.

Design And Construction

A modified fixed dome digester with stirring mechanism has been designed and constructed and used for the anaerobic digestion of cow dung slurry at 5%-7% Total solid (TS) concentration within the mesophylic temperature range. The quality of biogas gas produced was between 54%-69% methane (CH4) content. The Carbon to Nitrogen ratio (C: N) varied between 35:1 - 45:1. Total biogas yield obtained over the detention period was about 261 L. The maximum and minimum temperatures recorded over the 95 days period was 32oC and 25 oC respectively. The volume of biogas yield, Vb (m3) was observed to increase with the percentage total solid, PTS (%). The details of the design and construction of the biogas digester plant and its cost are reported. The performance of the plant was very satisfactory. Investigation into the anaerobic digestion revealed that cow dung has great potentials for generation of biogas.
