Using the data below estimate the volumetric flow rate and mass flow rate using a flange orifice flow meter. Select a plate orifice using a reasonable differential pressure.

Meter diameter pipe $=4$ in schedule $40$

Gasoline specific gravity $0\mathrm{.}68-0\mathrm{.}74$ at $60$F

Use GPSA fig $23-10$ to convert specific gravity of oil fractions at flowing temperature.

Flowing temperature $=70-80$ F

Operating pressure $=100$ psi
