Hydraulic agitation in the aircraft spray tank requires which of the following?

Hydraulic agitation in the aircraft spray tank requires sufficient pump output capacity to properly mix the spray solution. This is crucial because effective agitation ensures that the chemicals are thoroughly mixed, preventing settling and ensuring uniform application. The pump must have the ability to create the necessary flow and pressure to keep the mixture agitated consistently throughout the spraying process.

While it is true that some specialized mixtures might require certain handling, regardless of chemical properties, adequate pump performance is essential for hydraulic agitation. Low pressure systems are not inherently a requirement for hydraulic agitation; rather, the system needs to maintain an appropriate pressure to achieve effective mixing. The manual activation switch, while useful, is not a fundamental requirement for hydraulic agitation, as the system can be designed to operate automatically in many modern aircraft.
