Valve, Fitting, Pipe를 통과한 유체의 출구유량
==============================================================
◎ Liquid Flow
Q = 21.07 d^2 √(△p / (K ρ))
W = 1.265 d^2 √(△p ρ/ K)
Q : flow rate [l/min]
W : flow rate [kg/hr]
d : internal diameter [mm]
△p : pressure [bar_g]
K : resistance coefficient
ρ : weight density [kg/m3]
◎ Compressible Flow
q = 19.31 Y d^2 √[(△p * p1')/ (K * T1 * Sg)]
q = 1.0312 (Y d^2) / Sg √[△p * ρ1 / K]
W = 1.265 Y * d^2 √[△p / (K * V1)]
q : flow rate [m3/hr] (@ 15℃, 1.013 bar_a)
Y : net expansion factor
d : internal diameter [mm]
△p : pressure [bar_g]
p1' : inlet pressure [bar_a]
K : resistance coefficient
T1 : absoulte temperature [K]
Sg : specific gravity of gas [ ]
ρ : weight density [kg/m3]
V1 : specific volume [m3/kg]
