1. What is a Garden Hose Flow Rate Calculator?

Definition: This calculator estimates the water flow rate through a garden hose based on water velocity and hose cross-sectional area.

Purpose: It helps homeowners and gardeners determine water flow for irrigation, cleaning, or other outdoor water needs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Flow rate (gallons per minute)
• \( V \) — Water velocity (feet per second)
• \( A \) — Cross-sectional area (square feet)
• 448.83 — Conversion factor

Explanation: The formula calculates flow rate by multiplying velocity by area and converting to gallons per minute.

3. Importance of Flow Rate Calculation

Details: Proper flow rate estimation ensures adequate water supply for your needs and helps prevent hose or faucet damage from excessive pressure.

4. Using the Calculator

Tips: Enter the water velocity in ft/s and hose cross-sectional area in ft². Typical garden hoses have 5-10 GPM flow rates.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical garden hose flow rate?
A: Most standard garden hoses deliver between 5-10 gallons per minute (GPM).

Q2: How do I measure hose cross-sectional area?
A: Calculate using \( A = \pi r^2 \) where r is the inner radius (diameter/2) of your hose.

Q3: What affects water velocity in a hose?
A: Water pressure, hose length, diameter, and any restrictions like kinks or attachments.

Q4: Why the conversion factor 448.83?
A: This converts cubic feet per second to gallons per minute (1 ft³/s = 448.83 GPM).

Q5: How can I increase my hose flow rate?
A: Use a shorter hose, larger diameter hose, or increase water pressure (within safe limits).
