Department of Agricultural Engineering, Lincoln College.https://hdl.handle.net/10182/16717In order to provide an insight into the energy-conversion performance of low-speed wind-powered water lifting devices, a non-dimensional performance prediction method has been developed. This takes account of positive-displacement pump characteristics, windmill rotor characteristics and wind characteristics. The approach leads to the conclusion that, where conditions permit, the type of system best suited to small scale irrigation comprises a riston or 'bucket' suction pump coupled to a multi-bladed or sail-type windmill rotor, together with a reinforced concrete water storage tank. This is in accord with current practice in some special areas. The performance prediction method is demonstrated in two examples and a small-scale irrigation case study.90 pages© Lincoln Collegewind powerirrigation engineeringReportANZSRC::300201 Agricultural hydrologyANZSRC::300208 Farm management, rural management and agribusinessANZSRC::401209 Hydrodynamics and hydraulic engineering
