“…These turbines are appropriate for installation in an outlet of a reservoir, within a weir, hydraulic control structure, or canals, or in an existing pipe. The Kaplan turbines exist with three to seven-bladed runners of any diameter with the installation can be in the horizontal, inclined, or vertical position [ 73 ].…”

“…The solidity (i.e. chord length of blade/blade pitch) at the hub of the runner was confined near 1 for minimum profile losses (Chen & Engeda 2019). To incorporate the effect of the flow deviation, the angle of deviation was subtracted from the blade stagger angle.…”

The agriculture sector of Nepal has been plagued by problems of poor irrigation networks and infrastructure. This has forced farmers to use fuel and electricity-based pumps, which are both expensive and unsustainable. The problems related to the distribution of power and fluctuating voltages add to the ineffectiveness of the electrical pumping system. So, as a better alternative for environment-friendly and inexpensive irrigation infrastructure, this paper proposes a design methodology of a community-operated hydro-powered pump called water turbine pump (WTP). Although introduced in the 1920s, this technology has been largely ignored nowadays. Moreover, there are insufficient literature and technical documentation to support the design decisions for developers. With an objective to induce momentum in the research and development of this technology, this work presents a well-defined methodology to design a WTP using a propeller turbine directly coupled with a centrifugal pump, in reference to a site located in Bardiya, Nepal. The WTP designed using this methodology could utilize a head of 3 m and a flow rate of 150 lps to deliver 14 lps of water to a height of 14.9 m, yielding a head ratio of 1:5, with an overall efficiency of 50.5%.
