| dc.description.abstract | A low cost water wheel was designed, fabricated and tested in the distributory canal of KCAET farm, Tavanur. The device was operated by the stream current with no additional power source and was tested for different submergence depths varying from 0.12 to 0.25 m. Water wheel with eight cups of 30 cm x 7 cm x 2 cm intake compartment was found to be the most efficient under various operating conditions. A maximum efficiency of 48% was obtained at 0.23 m of submergence depth. The device can lift water without additional operating cost as long at the mean stream velocity is greater than or equal to 0.44 m/sec for the optimum depth of submergence at 23 cm. The corresponding discharge of the system is 19.2 lpm at 0.6 m head. The investment cost of the device is Rs. 800/- and the annual operating cost is Rs. 204/- with low maintenance cost. Though the power output and the discharge capacity were low, it has a two fold advantage of functional reliability and simplicity of design and fabrication at village level. It can successfully be utilised by the small farmers when the cultivating fields are adjuscent to the canal water courses. | en_US |
