1. What is a Water Velocity Calculator from Pressure?

Definition: This calculator estimates the velocity of water flow based on pressure difference and water density.

Purpose: It helps engineers and fluid dynamics professionals determine water velocity in pipes and systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \sqrt{\frac{2 \times \Delta P}{\rho}} \]

Where:

\( V \) — Water velocity (meters per second)
\( \Delta P \) — Pressure difference (Pascals)
\( \rho \) — Water density (kilograms per cubic meter, default 1000 kg/m³)

Explanation: The formula calculates the velocity of water flowing due to a pressure difference, based on Bernoulli's principle.

3. Importance of Water Velocity Calculation

Details: Proper velocity estimation ensures efficient pipe sizing, prevents erosion, and maintains optimal flow rates in hydraulic systems.

4. Using the Calculator

Tips: Enter the pressure difference in Pascals and water density (default 1000 kg/m³). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for pressure?
A: The calculator uses Pascals (Pa). 1 psi ≈ 6894.76 Pa.

Q2: Why is water density typically 1000 kg/m³?
A: This is the standard density of pure water at 4°C. It varies slightly with temperature and impurities.

Q3: Can I use this for other fluids?
A: Yes, but you must adjust the density value accordingly for different fluids.

Q4: What are typical water velocities in pipes?
A: Common velocities range from 0.5-3 m/s in domestic systems to 3-6 m/s in industrial applications.

Q5: Does this account for friction losses?
A: No, this is the theoretical maximum velocity. Actual velocities will be lower due to friction and other losses.
