A diaphragm pump is a type of positive displacement pump that uses a flexible diaphragm to move fluids. It operates by creating a separation between the fluid being pumped and the moving parts of the pump, which minimizes the risk of contamination and allows for pumping of aggressive chemicals or slurries. **Key features of diaphragm pumps include:** 1.
An electroosmotic pump (EOP) is a type of pump that utilizes electroosmosis to move fluids, primarily in microfluidic systems. The principle of electroosmosis involves the movement of a liquid through a porous medium or microchannel due to an applied electric field. This phenomenon occurs when an electric field is applied across a liquid that contains charged species—typically ions—resulting in the movement of liquid as the ions migrate.
An HCNG dispenser is a fuel dispensing unit designed to supply HCNG, which stands for Hydrogen-CNG (Compressed Natural Gas). HCNG is a blend of hydrogen and compressed natural gas, and it is considered a cleaner alternative to conventional fuels. The HCNG dispenser functions similarly to traditional CNG dispensers but incorporates technology to handle the hydrogen component safely and efficiently.
A honey wagon is a type of vehicle used primarily for the collection and transport of sewage and waste materials, particularly from portable toilets, septic tanks, and other sanitation facilities. The term can also refer to vehicles that service recreational vehicles (RVs) and trailers by emptying their waste tanks at campgrounds or during events. Honey wagons are equipped with tanks that hold the waste until it can be properly disposed of, often at designated waste treatment facilities.
A Rushton turbine is a type of impeller used in mixing and agitation applications, particularly in bioreactors and chemical engineering processes. It is characterized by its flat, disc-like shape that has several radial blades attached to it, typically with a high aspect ratio. The design of the Rushton turbine facilitates effective mixing and aeration of liquids, making it ideal for applications involving the mixing of liquids and gas phases.
A turbopump is a type of pump used in various applications, particularly in rocket propulsion systems, to move fluids at high pressures and flow rates. It combines a turbine and a pump into a single unit, leveraging the mechanical energy from the turbine to drive the pump. In rocket engines, turbopumps are critical components that transfer propellants (liquid fuel and oxidizers) from the tanks to the combustion chamber at high pressures.
A volute in the context of a pump refers to a spiral-shaped casing or channel that is part of the pump design, specifically in centrifugal pumps. Its primary function is to convert the velocity of the fluid exiting the impeller into pressure energy. Here's a breakdown of how a volute works: 1. **Fluid Flow**: As the impeller rotates, it imparts kinetic energy to the fluid, causing it to flow outwards from the center of the impeller.
"Circle" can refer to several different concepts or entities, depending on the context: 1. **Geometric Shape**: In mathematics, a circle is a simple shape consisting of all points in a plane that are at a given distance (radius) from a fixed point (center). 2. **Circle in Geometry**: In geometry, a circle is defined by a set of points equidistant from a common center.
Personal assistant robots are robotic systems designed to assist individuals in various tasks, often in their homes or workplaces. These robots typically utilize artificial intelligence (AI), natural language processing (NLP), and machine learning technologies to interact with users and perform specific functions. The primary goal of personal assistant robots is to enhance productivity, convenience, and comfort by taking over repetitive or tedious tasks.
As of my last knowledge update in October 2021, "Aformic" does not appear to be a widely recognized term or brand in popular literature, technology, or any other field. It’s possible that it could be a company, product, or concept that emerged after that date. Alternatively, it could also be a specialized term within a niche industry.
As of my last update in October 2023, Vaimos is a technology company that specializes in developing solutions and services aimed at enhancing customer engagement and experience. It often focuses on leveraging data analytics, artificial intelligence, and digital platforms to help businesses improve their interactions with customers.
A lathe is a machine tool that is used to shape materials, typically metal or wood, by removing material from a workpiece. The workpiece is held in place and rotated against a cutting tool. This process allows for various operations, including turning, drilling, knurling, and threading. Lathes are commonly used in manufacturing for creating cylindrical parts, and they can be operated manually or automatically with CNC (Computer Numerical Control) technology.
"People in the space industry" refers to a diverse group of individuals who work in various roles and capacities related to the exploration and utilization of outer space. This industry encompasses a wide range of activities, including satellite development, space exploration missions, space research, aerospace engineering, space tourism, and more.
Mathias Schacht is not a widely recognized public figure or concept, and there might be many individuals with that name.
Transport engineers are specialized professionals who focus on the design, planning, and management of transportation systems and infrastructure. They play a critical role in ensuring that transportation networks are safe, efficient, and environmentally sustainable. Their work encompasses a wide range of activities related to various modes of transport, including roadways, railways, airports, and transit systems.
Cistercian numerals are a system of numeral notation that was developed by the Cistercian monks in the 13th century. This system uses a set of symbols derived from a combination of straight lines to represent numbers. The Cistercian numeral system is distinctive because it allows for the representation of numbers in a compact and efficient manner, enabling the inscription of numbers along with text.
Glagolitic numerals are a system of numerical representation that was used in conjunction with the Glagolitic script, one of the oldest known Slavic alphabets. The script was created in the 9th century by Saints Cyril and Methodius for the purpose of translating religious texts into the Slavic languages. The Glagolitic numeral system resembles the numeral systems of other alphabets, such as the Greek and Hebrew systems, where letters represent numbers.
The polygamma function is a special function that is defined as the \( n \)th derivative of the logarithm of the gamma function, denoted as \( \psi^{(n)}(x) \). Specifically, it is defined as: \[ \psi^{(n)}(x) = \frac{d^n}{dx^n} \ln(\Gamma(x)) \] where \( \Gamma(x) \) is the gamma function.
Number sense in animals refers to the ability of non-human species to perceive, estimate, and manipulate numerical quantities. This cognitive skill allows many animals to understand and differentiate between different amounts of objects, which can be crucial for survival-related activities such as foraging, hunting, or social interactions. Research has demonstrated that various animals, from primates to birds and even some insects, exhibit number sense in different capacities.
Scientific notation is a mathematical method used to express very large or very small numbers in a more compact and manageable form. It takes the general form of: \[ a \times 10^n \] where: - \( a \) is a coefficient that is typically a number greater than or equal to 1 and less than 10 (1 ≤ \( a \) < 10).

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. 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-calculus
    Articles 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.
