Daftar Isi:
- A series of tests were already carried out at an open laboratory to simulate the utilization of tidal or river current to couple the spiral pump to lift u p the water to farm areas of about 2- 4 meters above the water l e v e l . The tests were conducted on two wheels with coils of different diameters. The first wheel of 46 cm diameter ; 6.6 mm coil pipe diameter; overall length of coil 19 meters; number of wound 16 th, the highest head achieved 4 meters. The second wheel o f 4 6 c m diameter; 8 . 1 m m coil pipe diameter; overall length of coil 14.3 meters; number of wound 13th; the highest head achieved 5.68 meters. The results comparation shows the efficiency of spiral pump proportional to the pipe diameter size. The smaller the diameter of pipe, the lower the efficiency
