Transcribed Image Text:**Title: Understanding Agitator Design and Torque in Washing Machines**
**Introduction**
The design of the agitator in a washing machine is the focus of an experimental study. This study particularly examines the relationship between the maximum torque \( T \) needed to oscillate the agitator shaft and several associated parameters.
**Parameters Explored**
1. **Oscillation Frequency (\( f \))**: The number of oscillations per unit time.
2. **Angular Velocity (\( \omega \))**: The speed at which the agitator rotates during oscillation.
3. **Diameter (\( D \))**: The diameter of the agitator.
4. **Height (\( h \)) and Width (\( w \))**: Dimensions of the paddles attached to the agitator.
5. **Number of Paddles (\( N \))**: The total count of paddles on the agitator.
**Objective**
The goal is to relate the maximum torque \( T \) to these variables, ensuring that viscous effects do not influence the flow. Moreover, the effect of the free surface is considered unimportant, along with fluid density \( \rho \).
**Conclusion**
Understanding these relationships is crucial for optimizing agitator design, ensuring efficient washing machine operation without unnecessary energy consumption.
