water over a number of cycles or “effects”, leaving the unwanted solids behind
Each stage essentially reuses the energy from the previous stage.
majority of water must be pumped from its source or directed into pipes or holding tanks
to remove large debris such as sticks, leaves, trash and other large particles

reservoir나 막힌곳을 만나면 다시 밸브쪽으로 되돌아간다.
또 닫혀 있던 밸브를 급히 열 때에도 같은 현상이 일어난다. 액체가 완전히 비압축성이고 관의 벽이 강체(剛體)라면 순간적으로 밸브를 닫았을 때의 압력은 무한대가 되지만, 실제로는 액체에 약간의 압축성이 있고, 관 벽에도 탄성이 있으므
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
2. Objective
1) To investigate of solid-liquid mixture flow characteristics in a slim hole annulus
2) Effect of pipe rotation, fluid property, annulus inclination on the particle transport velocity, transport efficiency and pressure drop
3. Theoretical background
3.1 Reynolds number
Reynolds number can be defined for a number of different situations where a fluid is in relativ
