본문내용
1. Approach velocity ( )=0.4m/s
2. Velocity through clean bar screen
(=velocity through the rack, ) = 0.8m/s
3. Slope from horizontal = 80degree
4. Clear spacing between bars = 10mm
5. Bar size – width = 10mm
– depth = 75mm
1. 소요되는 표면적계산
A= Q/OR=Q/40 =155.7988㎡
2.침전지 길이 결정
L=A/W =25.97m =26m
3.평균유량시 체류시간과 월류율
조내부체적=H*L*W=Q/10 =624㎥
체류시간=vol/Q=2.4h
4. 최대유량시 체류시간과 월류율
월류율=1.5Q/A=60 ㎥/㎡ ․ day
체류시간= vol/1.5Q=1.6h
