This project is aimed to fabricate the water pumping machine. Due to the topographical variation in Nepal’s Himalayan regions, people are facing problems of water in both drinking and irrigation supply though there are many rivers in Nepal. This has caused difficulty in many irrigation projects and drinking water supply projects.
We started our project with the collection of the data such as flow rate, head and velocity of a river by visiting some rivers like Roshi Khola and Punyamata River located in Panauti. We also visited reservoir type Khopasi Hydropower Project to know more about hydro driven machineries. Then we completed the flow rate analysis which is also the part of study of cross flow turbine. The velocity of Roshi Khola is found to be 1.2 m/s. We also studied about cross flow turbines and the profile of these turbines. For maximum efficiency the profile must be so adjusted that striking water should make an inlet angle of 30° and the discharging water makes 90° angle.
Furthermore, we have completed the fabrication of our project and the site testing will be done soon to analyze the efficiency of the device in Roshi Khola.
