Flow rates in oil pipes

Looking to calculate the maximum flow rate for WTI Crude in both 12" and 20" steel pipes - same fluid properties and pressure. Only difference woudl be the pipe diameter. How much more oil in volume terms would pass through the larger pipe compared to the smaller pipe? Any help much appreciated?

For laminar flow (Re<2300) flow rate will change with 4 power of diameter Q/Q1 = (D/D1)^4
For turbulent flow where friction factor is not depending on the Reynolds number flow rate will change with 2.5 power of diameter Q/Q1 = (D/D1)^2.5
Anyway, you can try with calculator at:

What is the flow rate in gallons per day for an oil pipeline with a 20 inch diameter?

It is difficult to say without knowing other properties like velocity or pressure difference, but with estimated velocity of 1 m/s it is about 200.000 gph or 4,8 mil gallons per day.
