  • Hose Diameter: Larger diameter hoses (e.g., 5/8 inch) allow more water to flow compared to smaller ones (e.g., 1/2 inch).
  • Water Pressure: Higher water pressure from the source increases flow rate, while lower pressure reduces it.
  • Hose Length: Longer hoses can lead to decreased flow rates due to friction loss over the distance the water travels.
  • Nozzle Type: The type of nozzle attached to the hose can also influence the flow rate, with some nozzles restricting flow to create pressure for spraying.

Flow Rate Table

The following table provides an overview of typical flow rates based on hose diameter and pressure:

Hose Diameter Flow Rate at 40 PSI (GPM) Flow Rate at 60 PSI (GPM) Flow Rate at 80 PSI (GPM)
1/2 inch 4-6 5-7 6-8
5/8 inch 6-9 7-10 9-12
3/4 inch 9-12 10-15 12-18

Calculating Gallons Per Hour

To calculate the gallons per hour (GPH) based on the flow rate in gallons per minute (GPM), the formula is straightforward:

GPH = GPM × 60

For example, if you have a hose that delivers 7 GPM, the calculation would be:

GPH = 7 GPM × 60 = 420 GPH

This information can help you determine how much water you can deliver to your garden over a specific period, optimizing your watering schedule and efficiency.
