Abstract
Description
PN2大気V収縮前=PN2収縮後V収縮後、すなわち、
PN2収縮後=(V収縮前/V収縮後)PN2大気
陰圧(NP)=P大気-PN2収縮後
NP=P大気- PN2大気(V収縮前/V収縮後)
P大気=PN2収縮後+P機械的な圧縮抵抗圧
陰圧(NP)=P大気-PN2収縮後=(PN2収縮後+P機械的な圧縮抵抗圧)-PN2収縮後
NP=P機械的な圧縮抵抗圧
初期状態:P大気V収縮前=(nN2+nO2)RT=(PN2大気+PO2大気)V収縮前
酸素除去後:PN2大気V収縮前=nN2RT
収縮後:PN2パッチV収縮後=nN2RT
陰圧:NP=P大気-PN2パッチ= P大気-nN2RT/V収縮後
NP=P大気-PN2大気V収縮前/V収縮後
NPがP大気の5%の場合:0.05P大気=P大気-PN2大気V収縮前/V収縮後
PN2大気=0.80P大気が分かっている場合:0.05P大気=P大気-0.80P大気V収縮前/V収縮後
V収縮前/V収縮後=0.95P大気/0.80P大気=1.1875
開始体積に対する収縮率=(V収縮後-V収縮前)/V収縮後=1-(1/1.1875)=1-0.84=0.16=16%
