以前、海川上で下の二つの式を見かけましたが、どなたか、これがどこから引用されたものかご存知ですか?出典がなければ使えませんよ。 放出量の算定 5.14.2.1 高圧側流体が液相の場合の放出量
W=72000CtAt(2g(PH-PL)ρ)⁰·⁵
W:質量放出流量、kg/h
Ct:流動係数、省略値=1.0
At:管側の断面積、m²
At=(Dtube²/4)π
Dtube:管の内径、mm
g:重力加速度(g=9.80665)
PH:高圧側の操作圧力、kPa
PL:低圧側の放出圧力、kPa
ρ:高圧側流体の密度、kg/m³

5.14.2.2 高圧側流体が気相の場合の放出量
W=20At(2g(kH/(kH-1))(MPH²/(ZHRTH))((PL/PH)(2/kH)-(PL/PH)((kH+1)/(kH)))⁰·⁵
W:質量放出流量、kg/h
At:管側の断面積、m²
At=(Dtube²/4)π
Dtube:管の内径、m
g:重力加速度(g=9.80665)
kH:高圧側流体の断熱指数(k=Cp/Cv)
M:分子量
ZH:高圧側流体の圧縮因子
R:気体定数、R=8.314、kj/kmol×K
TH:高圧側の操作温度、K
PH:高圧側の操作圧力、kPa
PL:低圧側の放出圧力、kPa
