Abstract

This eprint provides information on the design and use of this equipment for teaching and research.

This manual, which is one of a series on locally made equipment for teaching and research in agricultural engineering, describes a rig for determining the calibration of, and distribution from, agricultural spray nozzles. The rig is specified in terms of a basic circuit diagram and construction drawings; sources of supply for the components and other data on spray nozzles are also given. The method of using the rig is explained, together with the interpretation of the results.
