    exact approximation of quantity as in cars by fuel meters what we get an idea of whether tank is full‚ empty‚ half full etc. The liquid level detector and optimizer play an important role in tanks to indicate the level of liquid of a particular density. In this paper we have proposed a technique to measure the amount of liquid available in tank. This device digitally displays the level of liquid inside the tanks using load sensor. The measurements are taken so the accuracy level is of 96.36%-98%

    "Cartesian" is named after the French mathematician and philosopher Rene Descartes‚ who lived from 1596 until 1650. Cartesian diver lab is used commonly in scientific experiments to illustrate principle of buoyancy. The objective of this Cartesian diver lab is to demonstrate Pascal ’s law and Archimedes ’ principles. Observation is the key to conduct this experimental study of the Cartesian diver. First a 2-liter bottle is filled with water to almost all the way to the top‚ then prepare the diver

    thresholds as the original method. In addition‚ the modified between-class variance can be pre-computed and stored in a look-up table. Our analysis of the new criterion clearly shows that it takes less computation to compute both the cumulative probability (zeroth order moment) and the mean (first order moment) of a class‚ and that determining the modified between-class variance by accessing a look-up table is quicker than that by performing mathematical arithmetic operations. For example‚ the experimental

    Individual solid particles are characterised by their size‚ shape‚ and density. 1.1 Particle shape The shape of an individual particle is expressed in terms of the sphericity F s‚ which is independent of particle size. The sphericity of a particle is the ratio of the surface-volume ratio of a sphere with equal volume as the particle and the surface-volume ratio of the particle. For a spherical particle of diameter D p‚ F s =1; for a non-spherical particle‚ the sphericity is defined as Dp:

    take the mean of the two temperatures you have measured as the effective temperature of the water during the calibration. Calculations 1. Find the mean of the four trials. The mean volume can now be determined from the mean mass and the density of water at the temperature you determined in 6 above. However‚ there is a correction to be made for the upthrust of air on the water during the weighing. In normal day-to-day use of balances we neglect this correction‚ but now that we are interested
