1. What Is Dynamic Agitator Load?

Dynamic agitator load refers to the force exerted by an agitator during operation, taking into account the rotational dynamics and system efficiency. It represents the actual mechanical load experienced by the agitator shaft and drive system.

2. How Does The Calculator Work?

The calculator uses the dynamic load formula:

\[ Load = \frac{Torque \times Angular\ Velocity}{Efficiency} \]

Where:

\( Torque \) — Rotational force applied (N·m)
\( Angular\ Velocity \) — Rotational speed (rad/s)
\( Efficiency \) — System efficiency as a fraction (0 to 1)

Explanation: The formula calculates the dynamic load by multiplying torque and angular velocity to get power, then dividing by efficiency to account for energy losses in the system.

3. Importance Of Dynamic Load Calculation

Details: Accurate dynamic load calculation is essential for proper agitator sizing, motor selection, shaft design, and ensuring system reliability and longevity.

4. Using The Calculator

Tips: Enter torque in N·m, angular velocity in rad/s, and efficiency as a decimal fraction (e.g., 0.85 for 85% efficiency). All values must be positive, with efficiency between 0 and 1.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between static and dynamic load?
A: Static load refers to stationary forces, while dynamic load accounts for forces during motion, including acceleration and rotational effects.

Q2: How do I measure torque for an agitator?
A: Torque can be measured using torque sensors, calculated from motor power and speed, or estimated from fluid properties and impeller design.

Q3: What is typical agitator efficiency?
A: Agitator efficiency typically ranges from 0.7 to 0.95 (70-95%), depending on gearbox quality, bearing condition, and mechanical design.

Q4: Why is angular velocity in rad/s instead of RPM?
A: Rad/s is the SI unit for angular velocity and provides direct compatibility with torque in N·m for power calculations.

Q5: How does fluid viscosity affect dynamic load?
A: Higher viscosity fluids require more torque to maintain the same angular velocity, significantly increasing dynamic load on the system.
