Description
第N階層の分配用配管それぞれから分岐される分岐数BNは、以下の式、
BN ≒ R^(1/T) ・・・(Rの1/T乗)
ただし、BN、R、Tは2以上の整数、により求められた値に応じた数とした情報処理装置が提供される。
(1)一つの分配用配管211から複数の電子機器40に接続するように分岐するため、分配用配管211の長さが、電子機器40の数が増加するに従い長くなる。一方、分配用配管211の流入口から電子機器40までの距離(以下、分配経路)の違いによる圧力損失を無くすために、分配経路を同一の長さにする必要がある。そのため、全ての分配用連絡管212は最も長い分配用連絡管212の長さに合わせなくてはならず、より大きな実装スペースを要するようになる。
(2)分配用配管211の流入口から、分配用配管211の個々の流出口までの距離の増大による圧力損失が流量の低下を招くので、圧力損失の差を小さくするために、分配用配管211の径をさらに太くする必要がある。
BN ≒ R^(1/T) ・・・(Rの1/T乗) (式4)
ただし、Rは総分岐数、Nは階層番号、Tは階層数であり、R、T、Nは2以上の整数とする。
第N階層の分岐数は、総分岐数Rの因数から近い数が選択される。例えば、式4により求められた値αを中心として所定の範囲に含まれる整数が分岐数として選択される。所定の範囲は、例えば式4により求められた値αから、±α/2以内の範囲である。
(1)2×20:B1=2、B2=20 B1+B2=2+20=22
(2)4×10:B1=4、B2=10 B1+B2=4+10=14
(3)5×8:B1=5、B2=8 B1+B2=5+8=13
(4)8×5:B1=8、B2=5 B1+B2=8+5=13
(5)10×4:B1=10、B2=4 B1+B2=10+4=14
(6)20×2:B1=20、B2=2 B1+B2=20+2=22
ただし、B1は第1階層の分岐数、B2は第2階層の分岐数である。
ΔP=λ*TL/TD*ρu^2/2=4f*TL/TD*ρu^2/2 (式5)
ただし、TLは分配用連絡管の長さ(単位:m)、TDは円管の内径(単位:m)、ρは、流体密度(単位:kg/m3)、uは流速(単位:m/s)、λは、Darcyの摩擦損失係数、fはFanningの摩擦係数で、λ=4fである。
(1)2×20の場合
GM ≒ V^(1/T) ・・・(Vの1/T乗)(式6)
ただし、Vは総合流数、Mは階層番号、Tは階層数である。総合流数Vが40である場合、第1階層の合流数×第2階層の合流数の組合せは、8×5の組合せと5×8組合せとなる。そして、8×5の組合せを適用することで、下流側の階層で合流数が少なくなり、合流用連絡管222による占有スペースが減少し、部品を調達するコストが低減される。
