1. What is the Hose Flow Rate Equation?

The Hose Flow Rate equation calculates the volumetric flow rate through a hose or pipe based on its cross-sectional area and fluid velocity. It provides a fundamental calculation for fluid dynamics applications.

2. How Does the Calculator Work?

The calculator uses the hose flow rate equation:

\[ Q = \pi \times (D/2)^2 \times v \]

Where:

\( Q \) — Flow rate (m³/s)
\( D \) — Diameter of hose (m)
\( v \) — Velocity of fluid (m/s)
\( \pi \) — Mathematical constant (approximately 3.14159)

Explanation: The equation calculates the cross-sectional area of the hose and multiplies it by the fluid velocity to determine the volumetric flow rate.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate calculation is crucial for designing irrigation systems, plumbing systems, industrial fluid transport, and various engineering applications involving fluid flow.

4. Using the Calculator

Tips: Enter diameter in meters, velocity in meters per second. All values must be valid (diameter > 0, velocity > 0).

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the inputs?
A: Use meters for diameter and meters per second for velocity to get flow rate in cubic meters per second.

Q2: Can I use different units?
A: Yes, but you'll need to convert the result accordingly. The equation works with consistent units.

Q3: Does this equation work for all fluids?
A: This basic equation works for incompressible fluids. For compressible fluids, additional factors need to be considered.

Q4: What if the hose isn't circular?
A: This equation is specifically for circular cross-sections. For non-circular hoses, different area calculations are needed.

Q5: How accurate is this calculation?
A: This provides theoretical maximum flow. Actual flow may be less due to friction losses, bends, and other factors.
