RVs have three main water tanks for fresh water and two types of wastewater. A fourth tank heats water for showering and washing dishes. RV sewage tanks are split, and tanks are generally made of plastic. Portable tanks exist for fresh and waste water, and hot water tanks are also common. The three main RV […]
A water brake, also known as a dyno, measures horsepower and torque by using water to work against an engine’s rotational power. It can measure power for engines or complete vehicles, and can simulate track conditions for tuning. Water brakes can measure horsepower from 50 to over 5,000. They help automakers create better engines and […]
A water solenoid is an electromagnetic device used to control the flow of water in hard-to-reach or remote locations. It consists of a poppet valve operated by a solenoid that opens the valve when activated by an electric current. The solenoid is commonly used in automated systems, such as fire and sprinkler systems. A water […]
Hydraulic seals are used to contain hydraulic fluid and pressure in a cylinder. There are two types: static and dynamic, made from rubber or polyurethane. Rust and erosion can damage seals, but replacement seals can be purchased to prevent leaks. A hydraulic seal is a gasket-like device used to seal the hydraulic fluid and pressure […]
A water pump bearing supports the impeller shaft and seals coolant inside the pump housing. Signs of damage include squealing sounds and coolant leaks. The bearing is typically a sealed, machined race designed to withstand harsh operating conditions. Most water pumps cannot be rebuilt due to the extreme conditions they operate under. A water pump […]
Water heat recycling uses a heat exchanger to transfer heat from wastewater to cold incoming water, reducing energy consumption and costs. Systems vary in design and cost, and can be retrofitted into existing structures. Preheated water reduces overall energy consumption and can be further optimized by hooking up to a gray water recycler. Grants and […]
Air Pressurized Water (APW) is a common substance in fire extinguishers used for Class A fires. It’s just water and pressurized air combined to create a more powerful stream of water. APW extinguishers should not be used on Class B, C, or D fires. Before using APW on electrical equipment, it must be unplugged and […]
Chlorination of water is common, providing benefits such as reducing disease risk. Chlorine prevents contamination but may trigger health problems and allergies. The degree of risk versus benefits is debated, with some communities considering alternatives to reduce negative effects. Chlorination of water is a common process in many municipalities today. Adding chlorine to water is […]
Water footprint measures water use over time, including indirect use for consumer goods. It can be used to assess countries, companies, and demographics. Water is a fundamental resource, and reducing water waste can improve global water security. Water awareness can increase access to safe drinking water. A water footprint is a measure of how much […]
Waste from water treatment includes biological waste, industrial water waste, and household waste. It is sent to a wastewater treatment plant to filter solids and release clean water. Industrial wastewater may be treated on-site before being transported to a government plant. Waste from water treatment is any product that is discarded into a sewage system, […]
Electric hydraulic pumps compress fluid to drive a secondary mechanism, typically using gear or lobe pumping mechanisms. They can be driven by AC or DC motors and are commonly used in industrial and mobile applications. Hydraulic pumps draw fluid from a reservoir and deliver it under high pressure to operate positive displacement mechanisms. Electric water […]
Electric hydraulic pumps compress fluid to drive a secondary mechanism, typically using internal gear or lobe mechanisms and operated at low speeds. They can be driven by AC or DC motors and come in various sizes. Hydraulic pumps draw fluid from a reservoir and deliver it under high pressure to operate positive displacement mechanisms. Electric […]
Water blasting requires a powerful compressor, proper technique, and correct equipment setup. Regional water supplies should be considered, and bystanders should be cleared. Adjusting the pressure valve and nozzle is essential. Drought conditions may require alternative blasting mediums. Safety is crucial. The best tips for water blasting are choosing a powerful compressor, proper blasting technique, […]
Microplastics are found in food, drinks and even the air we breathe, with the average person ingesting around 2,000 pieces of microplastic each week – equivalent to the weight of a credit card. The long-term effects on humans are not yet known, but scientists advise recycling and avoiding excessive plastic packaging. In one of the […]
California, Texas, Florida, and Idaho are the US states that use the most water, contributing over 25% of all US water use in 2005. California used the most water, with 11% of the US total, and 75% of its freshwater use was for agriculture. Water usage declined in the US between 1980 and 2000 due […]
Waterways are wide and deep enough for boats to pass through, but channels can be narrow and hazardous. Government agencies maintain them and use dredging to control depth. Boat companies may maintain waterways leading to their docks. Navigation laws must be followed to avoid accidents. A waterway is a naturally or artificially produced waterway wide […]
Reverse osmosis uses pressure to force water through a semi-permeable membrane, separating pure water from contaminants. It removes more contaminants than other filtration systems, but is slow and wastes water. It is used in homes, industry, and to purify saltwater and rainwater. Reverse osmosis water filtration is a type of water filtration system that works […]
Water tunnels are experimental facilities used to test the hydrodynamics of underwater objects. They are more capable of performing three-dimensional experiments than wind tunnels and are used to improve shipbuilding. Water tunnels can vary in size and are used to test how propellers of different types of ships work. A water tunnel is very similar […]
An oily water separator is used on marine vessels to purify bilge water before it is pumped overboard. The device extracts oil through gravity separation, and other filtration methods are included. Dumping untreated bilge water overboard is a violation of international convention and may be prosecuted. An oily water separator is a device used on […]
Water wells are drilled to access natural groundwater for various purposes, including testing water quality and accessing clean water. Drilling rigs are used to drill precise holes, often aided by geological surveys and maps. Proper sealing is important to prevent contamination. Wells can be used by small communities or individuals in rural areas. Some wells […]
