Abstract:
Experiments were carried out to determine the relationship between density of liquid (pure water) and compression of five springs supporting a 1000 Liter tank from beneath.The tank is meant to be an anaerobic digester for production of biogas. The springs constant were determined and were used to compute the densities of a fixed concentration of two unknown liquids (that of a fixed concentration of salt and the other had varying concentration). Results show that each of the five springs had different spring constants ranging from 62,177N/m or Kg/s.s to 167,048N/m or Kg/s.s. The average density of the liquid with fixed concentration of salt is 1118.24Kg/cu.m which compares excellently well with the density of pure water (1000Kg/cu.m).The unknown liquid with varying concentration of salt follows an exponential relationship Y=3E-05e42.67xand a correlation of 0.97, where Y stands for density of the fluid and X the corresponding extension of the spring. We have used the expression to predict the density of similar water of unknown concentration.Since methane gas production potential depends on water dilution ratio, it is expected that we can calibrate any digester tank to give direct readings of densities of bio-degradable material from mere displacement of the suspension springs.
