Agitator Dynamic Load Formula:
| From: | To: |
The dynamic load of an agitator represents the power required to maintain the mixing motion against fluid resistance and inertial forces. It quantifies the actual power consumption during operation, accounting for torque and rotational speed.
The calculator uses the dynamic load formula:
Where:
Explanation: The formula calculates the mechanical power required by multiplying the torque needed to overcome resistance with the angular velocity of rotation.
Details: Accurate dynamic load calculation is essential for proper motor sizing, energy efficiency optimization, preventing equipment overload, and ensuring reliable agitator operation in various industrial processes.
Tips: Enter torque in Newton-meters and angular velocity in radians per second. Both values must be positive numbers. For RPM conversion to rad/s, multiply by 0.10472.
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 inertial and fluid dynamic effects.
Q2: How do I measure torque for an agitator?
A: Torque can be measured using torque sensors, calculated from motor current, or estimated from impeller design and fluid properties.
Q3: What factors affect agitator dynamic load?
A: Fluid viscosity, impeller design, rotational speed, tank geometry, and fluid density significantly impact dynamic load requirements.
Q4: Why is angular velocity in rad/s instead of RPM?
A: Radians per second is the SI unit for angular velocity, providing direct compatibility with torque in Nm for power calculation in Watts.
Q5: How much safety margin should I add to calculated load?
A: Typically 10-20% safety margin is recommended to account for startup transients, fluid property variations, and unexpected operating conditions.
