For laminar flow? For a full pipe? for a 3/4-full pipe? For a 1/2-full pipe? It all makes quite a difference. Please repost your question with a little more information.
It would also help to for us to know the coefficient of friction of the inside of the pipe.
2.5 gallons per minute
That depends entirely on the viscosity of the liquid in the pipe ! Water would flow faster than oil !
Depends on what's flowing (gas or water or something else) and under how much pressure.
The flow rate of water through a 1-inch hose line can vary based on factors such as pressure and hose length. However, under typical conditions, a 1-inch hose can deliver approximately 320 gallons per minute (GPM) at 60 PSI. This can change with different pressures and hose types, so it's essential to consider specific circumstances for precise calculations.
that's what she said

question cannot be answered because it depends on the water pressure

300 gallons per minute
Water flow rate half inch PVC pipe 65 psi?

The maximum flow rate through a 1.5 inch pipe is typically around 9 gallons per minute.
As many as could flow through before eroding the piping to the point of no more flowing through and it simply spewing about.

If the flow velocity remains the same the flow volume will increase by the square of the diameter ratio.(2/1.25) = 1.6 = diameter ratio1.62 = 2.56 more flow volume through 2 inch pipe compared to 1.25 inch pipe.
The recommended diameter for a 2-inch drainage pipe to effectively manage water flow is typically around 4 inches.
