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.

It depends on the flow rate in the hose and that depends on the water pressure.
i believe the pressure does not change but the volume of water you will be able to use will be less
