A foam pump is a type of dispensing device that is designed to create and dispense foam from liquid products, such as soaps, shampoos, lotions, and cleaning solutions. These pumps are typically designed with a mechanism that incorporates air into the liquid as it is dispensed, resulting in a foamy output.
A gasoline pump, commonly referred to as a fuel pump or petrol pump, is a device used to dispense gasoline or petrol for vehicles. These pumps are typically found at gas stations and are an essential component of the infrastructure for fueling cars, motorcycles, and other vehicles that use gasoline as a power source.

"Pump" can refer to different things depending on the context. Here are a few common interpretations: 1. **Mechanical Device**: A pump is a mechanical device that moves fluids (liquids or gases) by mechanical action, often converted from electrical energy or another form of energy. Pumps are used in various applications, including water supply, heating and cooling systems, industrial processes, and more.
A high-efficiency glandless circulating pump is a type of pump designed primarily for circulating fluids in various heating, cooling, and plumbing systems. These pumps are noted for their energy efficiency and their glandless design, which means they do not use mechanical seals (glands) to prevent leaks. Instead, they often employ magnetic drive technologies or other methods that eliminate the need for traditional seals, which can wear out and cause leaks over time.

Jabsco pumps are commonly used in applications such as: 1. **Marine Use**: Jabsco pumps are particularly popular in the boating and marine industry for tasks such as bilge pumping, fresh water supply, waste transfer, and deck wash systems.
A lobe pump is a type of positive displacement pump that uses two or more lobes to move fluid through the pump. The lobes, which can be either rotors or gears, rotate in a specific manner to create cavities that draw fluid in and then push it out. This type of pump is commonly used in industries such as food and beverage, pharmaceuticals, and chemical processing, where the gentle handling of sensitive materials is important.
A solar-powered pump is a type of pump that uses energy harnessed from the sun to operate. These pumps are typically powered by solar panels that convert sunlight into electricity, which is then used to run the pump. Solar-powered pumps are commonly employed in a variety of applications, including: 1. **Irrigation**: In agriculture, solar pumps are used to move water from wells, rivers, or reservoirs for irrigation purposes, providing farmers with a sustainable solution for watering crops.
A sump pump is a device used to remove accumulated water from a sump basin, typically found in the basement of a home or building. Its primary function is to prevent flooding and manage water levels, particularly in areas prone to groundwater buildup or excessive moisture. Here are some key points about sump pumps: 1. **Function**: The main purpose of a sump pump is to keep the basement or crawl space dry by pumping out water that collects in the sump pit.
A treadle pump is a type of irrigation pump that is operated by foot, allowing the user to use their body weight to drive the pumping action. Typically, it consists of two pedals that can be alternately pressed down by the feet, which in turn moves a piston or a diaphragm that draws water from a well or a nearby water source and discharges it for irrigation purposes.
Ventriloquists' dummies, also known as ventriloquist figures, are puppets used by ventriloquists during their performances to create the illusion that the puppet is speaking. The ventriloquist manipulates the dummy while "throwing" their voice, making it appear as if the dummy is speaking independently. These figures typically have movable mouths and sometimes joints, allowing for a wide range of expressions and gestures.

In graph theory, a **haven** is a concept used in the study of certain types of graphs, particularly concerning the connectivity and resilience of networks. Specifically, a haven is a vertex or a set of vertices in a graph that can serve as a refuge or a secure point from which other vertices can be reached despite the removal of certain edges or vertices.

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.
