submersible water pump Shiv Lal, Pawan Kumar, Rajeev Rajora Department of Mechanical Engineering, Rajasthan Technical University Kota, India Email:[email protected] Abstract: The performance of a photovoltaic (PV) array based water pumping system situated at Kota Rajasthan (25.18 N and 75.83 E), India has been studied. A 2hp DC motor with 2200W (10 panels of each 225W) have been used for disch...

Knowledge of iso-contours of the underwater terrain can be used to reconstruct it using interpolation. Identifying a set of isoclines can be more efficient and less time-intensive than sweeping a large area. In this paper, we propose a system where a small number of agile underwater vehicles cooperatively maintain a polygonal formation on a plane above the terrain and use field values measured ...

The electric submersible pump, also known as ESP, is a highly effective artificial lift method widely used in the oil industry due to its ability deliver higher production rates compared other methods. In principle, ESP multistage centrifugal pump that converts kinetic energy into dynamic hydraulic pressure necessary fluids at rate with lower bottomhole pressure, especially wells under certain ...

Due to the need for accurate exploration of deep-sea scientific research, drilling techniques by combining operational advantages Jiaolong manned submersible is considered one most feasible methods bedrock drilling. Based on deep sea cutting model and discrete element simulation, as well efficient design criterion, development a 7000 m electromechanical coring apparatus was carried out. The out...

A few specimens belonging to the deep-sea family Hyocrinidae (stalked Crinoidea, Echinodermata) collected by submersible in the eastern and western Pacific Ocean are described. Laubierierinus pentagonalis, n. genus, n. sp., from the North Fiji Rise is the first discovery of a hyocrinid crinoid with a pentaradially symmetrical stalk. Hyocrinus biscoitoi, n. sp., from the East Pacific Rise attain...

Semi-submersible offshore platforms play a vital role in deep-sea energy exploitation. However, the vast waves threaten platform’s operation, usually leading to severe consequences. It is essential study wave-slamming mechanism of under extreme wave conditions. Existing research simplifies platform slamming problem. This paper establishes model semi-submersible and flexible mooring system numer...
