Friedrich Wilhelm Pleuger
Friedrich Wilhelm Pleuger (born 6 April 1899 in Bonn; died 9 October 1972 in Hamburg) was a German engineer and entrepreneur who developed and patented a number of inventions, in particular water-filled electric motors, Submersible pump, submersible pumps and Rudder, ship rudder systems. He was a partner and founder of Pleuger Unterwasserpumpen GmbH in Hamburg (known as Pleuger, Pleuger Industries today), through which he marketed and sold these products. In addition, he was also the Consul (representative), consul general of Ghana in Hamburg. His technical developments have been used in various fields worldwide.

Water Supply
Water supply is the provision of water by public utilities, commercial organisations, community endeavors or by individuals, usually via a system of pumps and pipes. Public water supply systems are crucial to properly functioning societies. These systems are what supply drinking water to populations around the globe. Aspects of service quality include continuity of supply, water quality and water pressure. The institutional responsibility for water supply is arranged differently in different countries and regions (urban versus rural). It usually includes issues surrounding policy and regulation, service provision and standardization. The cost of supplying water consists, to a very large extent, of fixed costs (capital costs and personnel costs) and only to a small extent of variable costs that depend on the amount of water consumed (mainly energy and chemicals). Almost all service providers in the world charge tariffs to recover part of their costs. Water supply is a separat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consulate
A consulate is the office of a consul. A type of mission, it is usually subordinate to the state's main representation in the capital of that foreign country (host state), usually an embassy (or, only between two Commonwealth countries, a high commission). The term "consulate" may refer not only to the office of a consul, but also to the building occupied by the consul and the consul's staff. The consulate primarily serves its visiting nationals to the region in which it is based, and prospective visitors, commercial entities, or regional governments, who wish access or connections to the consulate's home country. There is usually also counselor services in the capital too, and in those cases, the consulate may share premises with the embassy itself. Consular rank A consul of the highest rank is termed a consul-general and is appointed to a consulate-general. There are typically one or more deputy consuls-general, consuls, vice-consuls, and consular agents working under the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Azimuth Thruster
An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle (azimuth), making a rudder redundant. These give ships better maneuverability than a fixed propeller and rudder system. Types of azimuth thrusters There are two major variants, based on the location of the motor: # Mechanical transmission, which connects a motor inside the ship to the outboard unit by gearing. The motor may be diesel or diesel-electric. Depending on the shaft arrangement, mechanical azimuth thrusters are divided into L-drive and Z-drive. An L-drive thruster has a vertical input shaft and a horizontal output shaft with one right-angle gear. A Z-drive thruster has a horizontal input shaft, a vertical shaft in the rotating column and a horizontal output shaft, with two right-angle gears. # Electrical transmission, more commonly called pods, where an electric motor is fitted in the pod itself, connected directly to the propeller without ...

Pleuger Rudder
The Pleuger rudder (also known as a Dutch rudder) is a power assisted ship's rudder. It creates a flow of water in the direction the rudder points powered by an auxiliary electric motor. This aids maneuverability at low speeds greatly, since it operates on a similar principle to a thruster. A ducted propeller is mounted as an integral part of the rudder and is fixed to it. The duct is a Kort nozzle A ducted propeller, also known as a Kort nozzle, is a marine propeller shrouded with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited d ... and enables the propeller to develop more thrust than an unducted propeller. The Pleuger rudder is necessarily mounted in the flow from the main engine's propeller in a ship with an odd number of propellers. If the Pleuger and the main engine are run at the same time, the Pleuger can often be torn away. The thrust produced by the P ...
