On the measurement of ram-pump power by changing in water hammer pressure wave energy

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.
