This study describes new considerations in the design and development of Archimedeanâs Pipe-Screw especially for water pumping in case of low head high volume form open farm pond at Rajamangala University of Technology Rattanakosin, Thailand. The objectives of this research is to develop an Archimedeanâs Pipe-Screw especially for water pumping in case of low head high volume form open farm pond used for water pumping with Thai sail windmill, at any location of low wind speed of Thailand and tests the performance of an Archimedeanâs Pipe-Screw Model (APSM). The experimental was carried out on diameter of Archimedeanâs Pipe-Screw is Φ5/8", the pitch Archimedeanâs Pipe-Screw (P) is 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8 and 2.0 D for angle slope of the screw with the horizontal (Î±) is 20, 25, 30Â°C in laboratory scale Archimedeanâs Pipe-Screw model. Archimedeanâs Pipe-Screw tests were conducted to assess the performance of characteristics of Archimedeanâs Pipe-Screw model. A model of pump has been manufactured; 1.0 m long with the blade small rubber tube was constructed. The output of the experiments recommenced for development the prototype of Archimedeanâs Pipe-Screw for the Thai sail wind pump. The prototype of pump has been manufactured, 4.0 m long, 8 m diameter. This wind pump has twelve triangular sails sweeping a circle of 8 m diameter. For the construction of this Archimedeanâs Pipe-Screw wind pump all efforts were made to use maximize materials and local parts available in the market for large scale of Archimedeanâs screw-pipe for Thai sail wind pump. The cost of material and parts is 145,000 Baht excluding the cost of machining and fabrication. Water discharge was in the range 0.005-0.081 lps. It can be seen maximum water discharge of pitch Archimedeanâs Pipe-Screw (P) is 1.4D at 80 rpm for Î± = 20Â° was 0.081 lps. For the result of prototype of Archimedeanâs Pipe-Screw for Thai sail wind pump, it was found that the curves for the prototype of Thai sail windmill coupled to twelve Archimedeanâs Pipe-Screw pump of wind speed and the discharge of was increased depending on wind speed. The discharge amount varied between 9.56-38.23 m3/h at head of 1.5 m in wind speeds from 1.0-5.0 m s-1 that the overall efficiency of this windmill for water pumping was highest (76.96%) at wind speed of 1.4 m s-1.
