Reynolds number for determining type of flow is given byĮfficiency of ram pump is given by formula E = Q*h/((Q + Qw)*H)Ī Hydraulic ram pump is a unique device that uses the energy from a stream of water falling from a low head as the driving power to pump part of the water to a head much higher than the supply head. Other losses of head in pipe fittings are expressed as Loss due to sudden enlargement at the T junction is expressed as Q = is the volumetric fluid discharge Ad = Area of pipe Velocity of fluid flow in the driven pipe is given by The velocity of fluid flow in the Tjunction is given byĪT = pipe x-sectional area at T-junction. Vd = velocity of fluid flow Ad = area of pipe. The velocity of fluid flow in the driven pipe is given by, Q = volumetric flow rate through the pipe r = pipe radius, The volumetric discharge from the drive pipe is given by, The working of a hydraulic ram pump is based on the first law of thermodynamics, where the kinetic energy of water at inlet is being converted into pressure energy using the pump setup. This pump is already in operation in countries like Nepal, Sri Lanka and Nigeria. The Hydram has only to moving parts and can be easily maintained. The hydraulic ram pump is an alternative pumping device that is relatively simple technology that uses renewable energy, and is durable. Fuel and maintenance costs to operate conventional pumping systems are becoming prohibitive. Provision of adequate domestic water supply for scattered rural populations is a major problem in many developing countries. The pump can be used in agricultural areas for pumping of water to farm lands and providing water to livestock. Unlike other pumps that use electricity for its working, this pump doesnt make use of any electrical input for its operation and hence it can be used in areas where there is lack of electrical connections but have unlimited source of flowing water bodies like rivers, lakes etc. No other energy is required and as long as there is a continuous flow of falling water, the pump will work continuously and automatically. The pump makes use of simple piping equipments and is adaptable to work in various areas.Ī hydraulic ram pump is a pump that makes use of kinetic energy of water at inlet and converts it into pressure energy and this pressure is used to lift water to higher elevations. Through the implementation of this project one could now easily pump to high terrains without of use of any external supply. Unlike other pumps, this pump is based on utilization of KE of water at inlet rather than simply being operated by an electrical supply. Student, Department of Mechanical Engineering, Hindusthan Institute of Technology, Coimbatore.Ībstract :- The idea of the project is to build a pump called Hydraulic Ram Pump that delivers water to higher altitudes with the use of its Kinetic Energy at inlet and then converting it to pressure energy.
