Flow Prover
Main Equation

Q= Fp C Ftf ; (from RCT)

Terms
Q= Flow Rate in [m3/d]
Fp = Flowing pressure upstream of Prover [kPaa]
C= Orifice coefficient ; (from RCT Table)
Ftf= Flowing Temperature Factor ; (equation shown below from AGA3)
T= Prover Temperature [ºC]

Supporting Equation
Ftf = (288.7 ºK / (T + 273.15 ºK))1/2; (from AGA3)
