Spray Characteristics Uniform solid cone-spray angle varies with air pressure and flow. A separate metering device, such as an orifice, metering pump or valve is required.

The spray angle is wider at high fuel-air ratios. For example, if the spray angle is 750 at a fuel-air ratio of 30 to 1, it may be reduced to 600 at a fuel-air ratio of 10 to 1. Higher air pressures produce narrower spray angles. Droplet size is sma
