1. What is Pipe Velocity?

Pipe velocity is the speed at which fluid flows through a pipe. It's an important parameter in fluid dynamics and engineering, affecting pressure drop, energy requirements, and system design.

2. How Does the Calculator Work?

The calculator uses the pipe velocity formula:

\[ Velocity = \frac{Flow}{\pi \times \left(\frac{Diameter}{2}\right)^2} \]

Where:

\( Flow \) — Volumetric flow rate (m³/s)
\( Diameter \) — Internal diameter of the pipe (m)
\( \pi \) — Mathematical constant Pi (~3.1416)

Explanation: The equation calculates velocity by dividing the flow rate by the cross-sectional area of the pipe.

3. Importance of Pipe Velocity Calculation

Details: Proper velocity calculation ensures efficient system design, prevents erosion or sedimentation, and helps maintain optimal flow conditions.

4. Using the Calculator

Tips: Enter flow rate in m³/s and pipe diameter in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical pipe velocity for water?
A: For water, typical velocities range from 0.5-3 m/s in most applications, with 1-2 m/s being common for general service.

Q2: Why is velocity important in pipe design?
A: Velocity affects pressure drop, noise levels, and potential for erosion or sedimentation in the pipe.

Q3: What happens if velocity is too high?
A: Excessive velocity can cause erosion, noise, vibration, and excessive pressure drops in the system.

Q4: What happens if velocity is too low?
A: Too low velocity may allow sedimentation in horizontal pipes and poor heat transfer in heat exchangers.

Q5: Does this calculator work for gases?
A: The basic formula works for any fluid, but gas calculations often need additional considerations for compressibility.
