Which spray tips can operate effectively at a pressure of 20 to 40 pounds per square inch?

The choice of flat and even spray tips as suitable for operation at a pressure of 20 to 40 pounds per square inch is based on their design and intended use. Both types of spray tips are optimized for delivering a uniform distribution of liquid at lower pressures, making them effective for a variety of applications such as agricultural spraying.

Flat spray tips are designed to create a wide, flat spray pattern that is useful for covering large areas evenly. They are commonly used in situations where precise targeting is less critical, allowing for efficient application of pesticides, herbicides, or fertilizers. Their performance is consistent across the pressure range of 20 to 40 psi, ensuring adequate flow and effective coverage.

Even spray tips, while they may be less common than flat spray tips, also operate effectively within the same pressure range. They aim to maintain uniform spray distribution to minimize overlap and gaps, which is important for achieving effective pest management and reducing chemical waste.

Together, these two types of spray tips represent a versatile option for applicators working within the specified pressure range, thus making the choice of flat and even spray tips the correct response.
