“…This will depend not only on the available flow speed, but also upon the crosssectional area and the length of the drive pipe. The length of the drive pipe is a crucial factor in the design of hydraulic ram pumps, with longer lengths providing greater pressure at the delivery outlet [20]. This suggests that a suitably designed water hammer energy system may be effective in relatively weak input conditions, as the flow rate will limit -but not directly governthe amount of pressure the system can generate.…”

“…Depending on design and input conditions, hydraulic ram pumps can exhibit a wide range of efficiencies. For example, the designs described in [25] reached efficiencies of 13 -15 % with a 1.8 m supply head, [26] reported an efficiency of 57 % with a 1.5 m supply head, [16] 44 % with a supply head of 9 m, and [20] 59.5 % in a 1.5 m supply head.…”

This article presents a system that makes use of the water hammer, which occurs when a fluid is subjected to a sudden change in momentum, to drive a piston-crank mechanism for power generation. Given that the magnitude of a water hammer is dependent upon the change in momentum experienced by the water, rather than the initial momentum itself, such a device may have applications operating as a pico scale hydropower device. The results of an experimental study are detailed, showing that a scale-model has a peak mechanical efficiency of 25.7 % and a mean efficiency of between 0.3-1.7 %. Potential applications for a refined version of the technology, namely picoscale hydropower generation and energy recovery from surge tanks, are also discussed.

“…Owing to its simplicity and eco-friendly process, the hydraulic ram pump is most suitable in mountainous areas for farmers and low-income earning citizens with abundant water sources. In fact, this pump can be used for irrigation and domestic water supply (Sampath et al, 2015). Recently, Kesharwani et al (2021) used a hydraulic ram pump for agricultural farming in a remote village in Taipadar, Central-East India.…”

In response to the continuous price increase of electricity and diesel fuel, a hydraulic ram pump serves as an alternative water pump that can be useful for farmers and lowincome earning citizens living in mountainous areas. However, this pump was observed to have a critical delivery head to work uninterruptedly. This study conducted a field experiment of 10 design cases for drive pipe to determine the critical delivery head of the newly developed hydraulic ram pump using different pipe fittings and a 20-L disposable polycarbonate bottle as a pressure chamber. Results showed that the newly developed hydraulic ram pump reached its highest discharge efficiency of 12.83% and energy efficiency of 84.61% at 9.83 and 10.90 m critical delivery heads, respectively. Results also revealed that the critical delivery head was 86.27% linearly correlated with discharge efficiency and 46.78% linearly correlated with energy efficiency (p < 0.05). Thus, the determination of the critical delivery head provided a baseline reference in ram pump studies that only gave ranges of ratios for the drive head to the delivery head. Furthermore, the newly developed hydraulic ram pump can produce water up to 700 L a day which can be beneficial for households and smallscale agricultural farming.

“…Therefore, an adjustable weight of the valve was proposed in designing a hydraulic ram [12]. The pressure of water proportional to the length of the drive pipe, meanwhile it increased the pressure loss occurring [13]. Moreover, diameter of the drive pipe affected the quantity of water flowing through the impulse valves and efficiency of the pump [14].…”

Four shaped models of delivery valve had been investigated and compared to improve performance of a hydraulic ram. Hydraulic ram pumps have been constructed and operated. Most of them built locally using steel pipe fittings that commercially accessible in the market rather than factory-made one. These have assisted inhabitants in rural or hilly area where water sources available for water supply services or irrigations. However, the major problem challenged by the public was on designing and repairing of the impulse and delivery valves of the pumps. Performance of the pumps are affected predominantly by the both valves. One characteristic of the valves is their shape. Considered on the characteristics of the fluid flow through surface of plate and sphere object are different on the pattern and losses. Therefore, investigation is necessitated to find a proper shape of the delivery valve for enhancing the performance of the pump. In this research four valve models were experimented to assess the hydraulic ram pump performance on varies delivery heads. The results show that the sphere model of the delivery valve offered the best efficiency, then followed by the membrane, the half-sphere and the flat delivery valve models. However, the rounded model: sphere and half-sphere delivery valve model were facing obstructions in implementation for a high delivery head.
