==============================================================

   

◎ 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] [이 게시물은 운영자님에 의해 2008-03-22 00:48:37 유체역학에서 이동 됨]
