1. What is Rotational Speed of Distribution?

The Rotational Speed of Distribution refers to the rate at which a distribution mechanism, such as a rotary distributor in a water treatment plant, rotates, typically measured in revolutions per minute or hertz.

2. How Does the Calculator Work?

The calculator uses the Rotational Speed of Distribution formula:

Where:

• \( n \) — Rotational Speed of Distribution (Hz)
• \( Q_T \) — Total Applied Hydraulic Loading Rate (m³/m²/day)
• \( N \) — Number of Arms
• \( DR \) — Dosing Rate (L/h)

Explanation: The formula calculates the rotational speed based on hydraulic loading rate, number of distribution arms, and dosing rate.

3. Importance of Rotational Speed Calculation

Details: Accurate rotational speed calculation is crucial for proper water distribution in treatment systems, ensuring even flow distribution and optimal treatment efficiency.

4. Using the Calculator

Tips: Enter hydraulic loading rate in m³/m²/day, number of arms (typically 2-8), and dosing rate in L/h. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for rotational speed?
A: Rotational speed typically ranges from 0.1 to 2.0 Hz, depending on the specific application and system design.

Q2: Why is the number of arms important?
A: The number of arms affects distribution pattern and flow rate per arm, with more arms typically providing more even distribution.

Q3: What factors affect dosing rate?
A: Dosing rate is influenced by system capacity, treatment requirements, and hydraulic characteristics of the distribution system.

Q4: How does hydraulic loading rate impact rotational speed?
A: Higher hydraulic loading rates generally require higher rotational speeds to maintain proper distribution efficiency.

Q5: Can this formula be used for different types of distributors?
A: While primarily designed for rotary distributors, the formula can be adapted for other distribution systems with appropriate modifications.
