Problem 1: Gas orifice flow meter The following data for an orifice flow meter is available Pipe diameter (D) =6 in. Orifice diameter (d)=3 in. Differential pressure (hw) =50 in H2O (24 h avg) Static pressure (Pf)=265 psia ( 24h avg) Flowing temperature (Tf)=85F Gas specific gravity (SGg)=0.60 Ambient temperature =75F Atmospheric pressure =14.7 psia Base pressure =15.0 psia Base temperature =60F Calculate the gas flow rate in scf/day and scf/h
