while the flow rates in a reservoir might appear slower, they do not change because the volume of moving fluid increases.
think of a river - when it is very wide, it moves very slowly
when it is narrow, it speeds up
this is because the total volume of the moving water is static
if you make a narrower channel it must move faster but the same volume of fluid is moved so the flow rate must also be static
it can be argued the flow rates should increase because there is less resistance in the reservoir
flow resistance in tubing is calculated be the diameter of the tube. it decreases exponentially as hose size increases
keep in mind that at our flow rates and tubing lengths this is a very minimal effect
