Volumes

Volume usually is the dimensional quantity that involves the evaluation of any three-dimensional figure enfolded inside a closed space. The SI unit (International System of Units) of volume is m3 and the dimensional unit of volume is [L3]. For estimation of the volume of any figure, various formulae are used. Another application of volume includes the reference in the sound levels, the higher the sound intensity, the louder the sound heard, and hence, the larger the volume. The SI unit of sound volume is decibels (dB).

A horizontal collimation test is performed on an automatic level and the collimation error of the instrument is found to be 0.001 m on the distance between the points of 100 m. Immediately before the test, the instrument was used in a survey where the observed elevation difference between two benchmarks was -13.038 m. The sum of the plus sight distances between the benchmarks was 1100 m and the sum of the minus sight distances was 580 m. Part A What is the corrected elevation difference between the two benchmarks?

1. Sometimes in leveling across topographic features such as rivers, it is difficult or may be utilized at such impossible to keep back sights and foresights short and equal. locations. 2. The most common method of determining difference in elevation, in this method a telescope with suitable magnification is used to read graduated rods held on fixed points. A horizontal line of sight within the telescope is established by means of a level vial or automatic compensator. 3. It is a leveling that consists in making rod readings on the upper, middle and lower crosshairs. 4. This leveling is useful in investigating and selecting the most economical grade, location, and depth for sewers, pipelines, tunnels, irrigation ditches, and other projects. 5. leveling is used where difficult terrain, such as mountainous areas, precludes the use of conventional differential leveling.
