Question

Highly viscous liquids and pastes are agitated by

• A. Multiple blade paddles
• B. Turbine agitators
• C. Propellers
• D. Single blade paddles

Hint:

Use slow-speed multi-blade agitators for dense, viscous, or plastic materials.

Answer 1

The Correct Option is A

Multiple blade paddles move high viscosity materials efficiently by applying large shear forces.
They reduce dead zones and improve mixing uniformity in pasty systems.
