| Delicate stains (food, grass) | Low | High |
Water Flow: The Unsung Hero
Water flow is often overlooked as a crucial factor in washing performance. However, the right balance of water flow and agitation is essential for effective stain removal and fabric agitation. Water flow affects the distribution of detergent and water throughout the wash cycle, which in turn impacts the overall cleaning effectiveness.
The relationship between water flow and agitation can be described using the following equation:
Q = ρ × A × v
- Q represents the volumetric flow rate.
- ρ is the density of the fluid (water).
- A is the cross-sectional area of the wash drum.
- v is the velocity of the fluid (water) through the wash drum.
By manipulating the water flow and agitation, washing machines can be optimized for specific stain types and fabrics, ensuring the best possible cleaning results.
