Agitator Tip Speed Calculator

Calculate Agitator Tip Speed (V)



Formula

The formula to calculate the Agitator Tip Speed (V) is:

\[ V = \frac{\pi D N}{60} \]

Where:

Example

Let's say the agitator diameter (\( D \)) is 0.5 meters and the rotational speed (\( N \)) is 300 rpm. Using the formula:

\[ V = \frac{\pi \times 0.5 \times 300}{60} \]

We get:

\[ V = \frac{471.24}{60} \approx 7.85 \text{ m/s} \]

So, the Agitator Tip Speed (\( V \)) is approximately 7.85 m/s.

What is an Agitator Tip Speed?

An agitator tip speed refers to the speed at which the tip of an agitator blade moves through the medium it is mixing. This speed is crucial in various industrial processes, such as mixing, blending, and chemical reactions, as it affects the efficiency and effectiveness of the process. The tip speed is determined by the diameter of the agitator and its rotational speed. Higher tip speeds can lead to better mixing but may also cause more wear and tear on the equipment and the medium being mixed.

Power Calculation for Agitator

Definition: The power required for an agitator is the energy needed to achieve the desired mixing.

Formula: \( P = N_p \rho N^3 D^5 \)

Example: \( P = 0.5 \times 1000 \times 100^3 \times 0.5^5 \)

Agitator Scale Up Calculation

Definition: Scaling up an agitator involves adjusting the design to maintain similar mixing performance in a larger system.

Formula: \( \frac{P_1}{P_2} = \left(\frac{D_1}{D_2}\right)^5 \)

Example: \( \frac{P_1}{P_2} = \left(\frac{0.5}{1}\right)^5 \)

How to Calculate Power Required for Agitator

Definition: The power required for an agitator is calculated based on the fluid properties and agitator dimensions.
