Artificial lift refers to a variety of techniques used to increase the flow of liquids, particularly crude oil and natural gas, from a well when the natural pressure is insufficient to bring the fluids to the surface. This typically becomes necessary as oil and gas reservoirs deplete over time and the natural pressure declines.
"Pump as turbine" (PAT) refers to the use of a centrifugal pump or axial pump in reverse operation to generate energy, functioning like a turbine. This concept is particularly useful in hydropower applications where a system traditionally designed for pumping water can be effectively utilized to produce electricity, especially during low-flow conditions or in micro-hydropower systems.
A scoop wheel, also known as a scoop wheel pump, is a type of water lifting device or mechanical device that is used to raise water from a source, such as a well or a river, to a higher elevation. It typically consists of a circular wheel with attached scoops or buckets that can scoop up water as the wheel turns.
The slip factor is a term used in various fields, but it is most commonly associated with fluid dynamics and aerodynamics. It refers to the difference between the theoretical performance of a pump, fan, or aerodynamic surface (like an airplane wing) and its actual performance due to losses caused by various factors. ### In Pump and Turbomachinery Context: In the context of pumps and turbines, the slip factor is defined as the ratio of the actual flow rate to the theoretical flow rate.
The term "water ladder pump" is not well-defined in common engineering or hydrology literature, and it could refer to various concepts or devices depending on the context.

A "table of bases" typically refers to a table that lists the bases of different number systems or mathematical structures. This table can serve various purposes, such as providing a quick reference for converting between number bases or for understanding how numbers are represented in different numeral systems. For example, the most common number systems are: 1. **Base 10 (Decimal)**: The standard system for everyday counting, which uses digits 0-9.
A leading zero is a zero (0) that appears at the beginning of a number, typically to provide a specific format or to ensure that the number reaches a certain length. Leading zeros are often used in various contexts, such as: 1. **Digital Representation:** In computer programming and digital electronics, leading zeros can help maintain consistent formatting, such as in binary numbers or when displaying numbers in a designated field length.
A mechanical counter is a device used to count events or objects in a mechanical manner, often employing a system of gears and levers. These counters operate without electronic components and are typically characterized by a series of numbered dials that rotate to display the counted number. Mechanical counters can be found in various applications, such as: 1. **Industrial Machinery**: Used to count the number of items produced or processed. 2. **Timers**: In devices that track elapsed time through mechanical means.
Suzhou numerals are a traditional system of representing numbers used in Suzhou, a city in Jiangsu province, China. This numeral system is known for its unique characters that are distinct from standard Chinese numerals. Suzhou numerals were historically used for accounting and tallying in commerce, particularly for merchants and traders. The system is composed of a set of symbols that represent numbers from 1 to 9, along with symbols for larger values.
Alfréd Rényi (1921–1970) was a Hungarian mathematician known for his contributions to various areas of mathematics, particularly in probability theory, set theory, information theory, and combinatorics. He is best known for the Rényi entropy, which generalizes the concept of entropy in information theory, providing a more flexible framework for measuring the uncertainty associated with random variables.
André Sainte-Laguë was a French mathematician and engineer, best known for developing the Sainte-Laguë method, which is a voting system used for proportional representation in elections. The method was first introduced by him in 1899 and is designed to allocate seats in a legislature in a way that reflects the overall vote distribution among parties or candidates. The Sainte-Laguë method employs a specific divisor to determine how many seats each party receives based on the number of votes they garner.
Charles Colbourn is a mathematician known for his work in the field of combinatorics, particularly in graph theory and its applications. He has made significant contributions to topics such as network design, extremal graph theory, and combinatorial designs. Colbourn has co-authored several books and numerous research papers, and he has been involved in various educational and academic activities.
H. B. Walikar refers to a prominent figure in the field of academia, specifically known for contributions in the areas of research and higher education. However, without additional context, it is difficult to determine the exact nature of H. B. Walikar's work or achievements, as there may be specific contributions or roles in various fields.

A coil tap is a method used in electric guitar pickups, particularly in humbucker pickups, to switch between different configurations of the coils. Humbuckers typically consist of two coils wound around magnets. A coil tap allows players to “tap” into one of the coils, effectively transforming the humbucker into a single-coil pickup. This can create a brighter, sharper tone commonly associated with single-coil pickups.
A Hohlraum is a device used in physics, particularly in the field of high-energy density physics and inertial confinement fusion experiments. The term "Hohlraum" is German for "cavity" or "empty space," and it refers to a cavity or chamber that is designed to create an environment for studying the behavior of matter under extreme conditions.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
