Drag coefficient

Drag coefficient

The so-called wind resistance is the wind resistance. When a vehicle is moving forward, the resistance to the wind is generally from the front unless the wind speed on the side is particularly large. Otherwise, it will not have much impact on the vehicle. Even if it does, it can be corrected through the steering wheel. Wind resistance has a great impact on the performance of cars.

The drag coefficient Cd is a measure of the impact of aerodynamic drag on a car. The smaller the drag coefficient, the smaller the influence of air resistance, and vice versa, so the smaller the drag coefficient, the better.

Generally speaking, most of the cars we see on the road have a drag coefficient of between 0.28 and 0.4. For vehicles with good linearity, such as sports cars, the drag coefficient can reach around 0.25, and some cars can reach around 0.15.

The drag coefficient is directly proportional to the car's fuel consumption. Therefore, reducing the air drag coefficient has important practical significance for reducing the fuel consumption of the car. According to tests, when a car is travelling at 80 km/h, 60% of the fuel is used to overcome wind resistance.

So how to reduce the drag coefficient of the car? The drag coefficient depends on the shape of the car. Undoubtedly, the streamlined body must obtain the ideal drag coefficient. Ferrari and Renault are undoubtedly the leaders in automotive streamlined design. Therefore, when choosing a car, the streamlined shape of the car body cannot be ignored because it directly affects the fuel consumption of the car.

Slicer Machine

The industrial veggie slicer is carefully designed based on the advanced technology of various manufacturers and the needs of users. It has the advantages of high work efficiency, convenient use, reliable quality, beautiful appearance and compact structure. Widely suitable for food processing plants, canteens and vegetable processing industries.

The following is an introduction to various types of industrial veggie slicer:

The vegetable dicing machine is suitable for dicing sauerkraut, garlic cloves, onions, ginger, potatoes, mushrooms, and potato roots. It has the characteristics of automatic orientation, neat slice shape, uniform thickness and good surface finish.

The multi-function vegetable cutter uses high-speed rotating blades to cut materials. Suitable for cutting vegetables. The large shredding and slicing machine is suitable for shredding and slicing ginger, small balls, roots and stem vegetables.

The two-dimensional cutting machine is designed for the needs of cutting large leafy vegetables such as spherical cabbage (cabbage) and Chinese cabbage into squares or long squares. Compared with similar products, the main advantage of this machine is that the material will not stay in the gap between the disc knife and the cross-cutting knife, which meets the requirements of food safety.

The double frequency conversion vegetable cutting machine is suitable for cutting and shredding onions, garlic, chives, celery, Chinese cabbage, dried tofu, spinach, banana slices, melons, eggplants, etc. Also replace the kitchen knife, which can cut root vegetables, such as bamboo shoots, carrots, potatoes, sweet potatoes, etc. shredded and sliced.
