In this slide, I will explain 2 kinds of problems of original flash mix. Structural and chemicals.
First, It has structural problems. As you can see the water flow direction, inlet locates downside and outlet locates upside.
Through this, we can know that axial impeller is not suitable. Also, because of wide width of tank, it has poor mixing.
Second, there is a problem with chemicals. PAC is
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
-Conclusion & Discussion
Poisson's ratio is derived by dividing the horizontal strain modulus by perpendicular strain modulus. Poisson's ratio is a characteristic value of materials, and concretes have 0.16∼0.22 of it. The Poisson's ratio from the first experiment is 0.18 and this is comprised in the range of theory, and the value from the second experiment is 0.16 which also comes under th
Ⅰ. INTRODUCTION
In fourth semester most of our department students attend the subject of mechanical manufacturing practice and we have made a bolt by ourselves. But the process was not a soft job. A bolt and nut is used diversely but it seemed that we don't know much about a importance and manufacture of bolts.
A bolt is a threaded fastener used inindustry to make two or more mechanical
1. Evolutionary Trends in Vegetation Organs (영양기관의 진화경향)
영양기관에는 매우 많은 형질 즉, 성장형(growth habit), 잎의 배열, 크기 형태 등의 가역성이 있는 형질이 있지만, 가역 되기가 어렵거나 완전히 가역 되지 않는 경향성을 지닌 형질도 많이 있다. 일반적으로 영양기관은 생식기관에 비해 가역성 있
