The simplicity of the machines suggests economical advantages, while the slow speed, the continuity of the bed and the large cells promise good ecological characteristics.Įxperimental set-up and results test for Series 3. Theoretical analysis and four series of model tests were conducted.Įfficiencies ranged from 0.5 to 0.9 for (1) and up to 0.8 for (2). Two different applications were developed: (1) the hydrostatic pressure wheel for head differences between 0.2 and 1 m and (2) the hydrostatic pressure machine for head differences between 1 and 2.5 m. Recently, a novel power-conversion mechanism which utilizes hydrostatic force differences was developed at Southampton University. Standard turbine types are considered not economical in this situation, since large turbine diameters and extensive civil engineering works are required.
