Fluid viscosity

Fluid viscous fluid flow under external force (or flow trend), the cohesion of molecules to prevent the relative movement of molecules to produce an internal friction, a phenomenon called fluid viscosity. The fluid will only show stickiness when it flows (or has a tendency to flow), and the rest fluid will not show any stickiness. Viscosity causes the velocity inside the flowing fluid to be unequal to each other. Take Figure 1-1 as an example. If the two parallel plates are filled with fluid, the lower plate will not move, while the upper plate will translate to the right at speed v0. Due to the viscosity of the fluid, the velocities of the fluid layers close to the lower and upper plates are 0 and v0 respectively, while the velocities of the middle strata are linearly distributed from top to bottom according to decreasing law. Experimental results show that the friction F between adjacent layers is proportional to the contact area A and the velocity gradient dv / dy of the relative motion between the flow layers. dv F = μA _ dy Where: μ is the proportional constant, known as the dynamic viscosity. If τ is the internal friction shear stress, that is, the internal friction per unit area, then F dv τ = = μ (1-3) A dy This is the Newtonian fluid friction law.

Vegetable&Fruit Lighting

Fruit and vegetable display lighting, agricultural product display lighting, fruit and vegetable showcase lighting, leafy green vegetable display lighting and organic food display lighting are all lighting solutions used to highlight the quality and appeal of produce.

The produce display lighting system highlights the color, texture and appearance of the produce through the use of special spectrum and lighting layouts. They use high-efficiency LED lights as a light source, and precisely control the color temperature and brightness, creating a bright and natural feeling, increasing the product's ornamental and purchase desire.

When displaying produce, these lighting systems focus on uniform light distribution, ensuring that each product is properly illuminated and avoiding dark or over-exposed areas. Whether vegetables, fruits or green leafy vegetables display lighting, they can show a fresh, healthy appearance, enhance the customer's buying experience. For organic food display lighting, it puts more emphasis on the natural and healthy properties of the product. Through well-designed lighting schemes, the original characteristics of organic food can be better displayed, attract more attention, and convey the concept of healthy eating. These display lighting systems can not only enhance the attractiveness of sales venues and increase product sales, but also emphasize the freshness, quality and nutritional value of agricultural products. Whether in supermarkets, malls, farmers markets or organic food stores, these lighting solutions can create a pleasant shopping environment for consumers and enhance customer satisfaction and purchasing experience.

In short, the lighting solutions such as vegetable and fruit display lighting, agricultural product display lighting, fruit and vegetable showcase lighting, leafy green vegetable display lighting and organic food display lighting are designed to highlight the appearance characteristics of agricultural products through special spectrum and layout design, enhance the attractiveness and sales effect of products, and create a pleasant and healthy shopping environment for consumers.
