1. What is Agitator Torque Calculation?

Agitator torque calculation determines the rotational force required to drive an agitator or mixer based on the power input and angular velocity. This is essential for proper motor selection and mechanical design in mixing applications.

2. How Does the Calculator Work?

The calculator uses the fundamental torque formula:

Where:

• \( Torque \) — Rotational force (N·m)
• \( Power \) — Mechanical power input (watts)
• \( \omega \) — Angular velocity (radians per second)

Explanation: This formula calculates the torque required to maintain a specific rotational speed given the power input to the agitator system.

3. Importance of Torque Calculation

Details: Accurate torque calculation is crucial for selecting appropriate motors, designing shafts and couplings, ensuring mechanical integrity, and optimizing mixing performance in industrial processes.

4. Using the Calculator

Tips: Enter power in watts and angular velocity in radians per second. Both values must be positive numbers. For RPM conversion, remember that 1 RPM = 0.10472 rad/s.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between torque and power?
A: Power is the rate of doing work, while torque is the rotational force. Power = Torque × Angular Velocity.

Q2: How do I convert RPM to rad/s?
A: Multiply RPM by 0.10472 to get rad/s. Formula: ω (rad/s) = RPM × 2π / 60.

Q3: What factors affect agitator torque requirements?
A: Fluid viscosity, impeller design, vessel geometry, baffle configuration, and operating speed all influence torque requirements.

Q4: When is peak torque important?
A: Peak torque is critical during startup, especially for high-viscosity fluids, and determines motor sizing and overload capacity.

Q5: How does viscosity affect torque?
A: Higher viscosity fluids require more torque to maintain the same rotational speed due to increased fluid resistance.
