Abstract

The renewable energy protocol in the world pushed most countries to extensive use of renewable energy sources, in exchange for a reduction of energy from conventional sources. In this article, the possibilities of exchange the water hammer energy to a column of water pressure evaluated experimentally. For this purpose, a ram pump made by two-inch internal diameter. Results indicated that ram pump power such as relative useful power (Pd/PT) and relative waste power (Pw/PT) were depended to length to diameter ratio of drive pipe (L/D), the relative energy due to steady flow velocity and impulse valve features (Ea/Ei), and the ratio of required pumping energy to maximum energy of water hammer (Ep/Em). The results showed that the mountainous area has potential to generate energy from water hammer as renewable energy, for a water system in highland that continuously needs to pumping water.
