Gasoline is pumped through a 2 in. sch 40 pipeline upward into an elevated storage tank at 608F. An orifice meter is mounted in a vertical section of the line, which uses a DP cell with a maximum range of 10 in.H2O to measure the pressure drop across the orifice at radius taps. If the maximum flow rate expected in the line is 10 gpm, what size orifice should you use? If a water manometer with a maximum reading of 10 in. is used instead of the DP cell, what would the required orifice diameter be?
