What is the relationship between nozzle spray angle and pressure?

The relationship between nozzle spray angle and pressure. The manufacturing process of the nozzle is very complicated, and its use is now very common. The nozzle injection principle is also based on science, and many factors affect their use. For example, it seems that the nozzle pressure and angle also affect each other.
1. The most important influence of pressure on nozzle performance is to change the flow rate of the nozzle. In general, the approximate relationship between pressure and flow in the working range of the nozzle is as follows: p2/p1=(q2/q1)2, where p1 and q1 are the pressure and flow in the first state, and p2 and q2 are the second. Pressure and flow in the state.
2. Pressure and nozzle droplet diameter: As the pressure increases, the droplet diameter decreases.
3. Pressure and spray angle: When the pressure increases, the spray angle will change slightly.
Therefore, in order to play a better role in the nozzle, it is necessary to better balance the relationship between the factors, and the factors are not independent of each other and will affect each other, just like the relationship between the injection angle and the pressure.
