Garden Hose Flow Equation:
| From: | To: |
The Garden Hose Flow Rate equation calculates the flow rate in gallons per minute (GPM) based on hose diameter and water pressure. This helps determine how much water your garden hose can deliver for irrigation, cleaning, or other outdoor water needs.
The calculator uses the garden hose flow equation:
Where:
Explanation: The equation accounts for the relationship between hose diameter (which affects cross-sectional area) and water pressure (which affects flow velocity) to determine the volumetric flow rate.
Details: Knowing your garden hose flow rate is essential for proper irrigation planning, determining watering times, selecting appropriate sprinkler heads, and ensuring adequate water supply for various outdoor activities.
Tips: Enter hose diameter in inches (common sizes: 1/2", 5/8", 3/4") and water pressure in psi. Typical residential water pressure ranges from 40-80 psi.
Q1: What are common garden hose diameters?
A: Standard diameters are 1/2 inch (most common), 5/8 inch, and 3/4 inch. Larger diameters provide higher flow rates.
Q2: How can I measure my water pressure?
A: Use a water pressure gauge attached to an outdoor faucet. Typical residential pressure is 40-80 psi.
Q3: Why does flow rate matter for gardening?
A: Proper flow rate ensures adequate water delivery to plants, helps determine watering duration, and prevents under or over-watering.
Q4: Does hose length affect flow rate?
A: Yes, longer hoses create more friction loss, reducing flow rate. This calculator provides ideal flow rates without considering length friction.
Q5: Can I use this for sprinkler system planning?
A: Yes, this calculator helps determine maximum flow capacity for designing irrigation systems and selecting appropriate sprinkler heads.
