The purpose of this study was to describe the development a solar-powered submersible pump system without use batteries in agriculture. used solar drive run it. implementation uses combination trackers, water storage tanks, power converters, and stabilizers. results explained that trackers increased efficiency units track sun throughout day convert energy into DC electrical power.

A teaching machine that simulates intravascular conditions found during a human therapeutic embolization has been constructed. A submersible pump drives fluid through a circuit of tubing. One limb of a Y (a vascular bifurcation) located in this circuit leads to a model arteriovenous malformation. Catheters placed in this limb may introduce embolic materials by various techniques, and those tech...

This study focuses on the effect of surface coating on the impellers and diffusers in improving the efficiency of mixed flow submersible borewell pumps. It consists of two parts. In the first part, a 3 stage pump was constructed with uncoated bronze impellers and cast iron diffusers having a surface roughness value of 2.5μm Ra and tested for pump performance. Then the same 3 stage pump was test...

94 Production from heavy-oil fields in the UK continental shelf (UKCS) has become possible over the past 10 years. Despite substantial reserves in the UKCS of crudes with gravitiy of 20°API and lower, most of the activity has been exploration and appraisal drilling. The main reason for restricted activity has been high uncertainty of reservoir and fluid properties. A method was developed to fin...

A Moving Horizon Estimator (MHE) is designed for a petroleum production well with an Electric Submersible Pump (ESP) installed for artificial lift. The focus is on estimating the flow rate from the well, the viscosity of the produced fluid, and the productivity index of the well. The software package ACADO is used to implement a Moving Horizon Estimator using a third-order nonlinear model. Simu...

Water is an essential element of life. The government of Ethiopia in collaboration with development allies’ attempts to increase pure water supply. Even though the coverage boosted dramatically still there is critical challenges in maximizing equipment’s reliability, improving service quality, maximizing capacity utilization, minimizing life cycle costs of water production mach...
