A water tender is a truck used to transport water to a fire scene, designed to pull water from lakes, streams, and fire hydrants. It serves as support equipment for larger fire trucks and is used in rural areas with few fire hydrants. It can also be used for airport crash contests and hazmat cleanup. […]
A water crane is a device that delivers water to elevated areas and can rotate and adjust its boom to deliver water at varying heights. It can work by using a pump or a reservoir and is typically made of steel or PVC. The flow of water is controlled by a valve, and it is […]
Chilled water is used in hydronic cooling systems to transfer heat energy from inside a building to the outside. It can be produced on site or provided by municipal agencies. Chilled water systems require less maintenance, cost less than refrigerants, and have minimal risk of leaks. Chilled water is one of the major components of […]
About 75% of US community water supplies have added fluoride, which helps prevent tooth decay. Water fluoridation is considered a top public health achievement. Over 200 million Americans have access to fluoridated water, and it is estimated to save $1 for every $1 invested. The cost for communities with over 38 people is approximately $20,000 […]
In-water surveys inspect a ship’s hull for damage, organic buildup, and abnormalities without dry-docking. Divers clean the hull, inspect the paint and steel, and examine the propeller and rudder system, providing photos and videos to the ship’s owners and board of inquiry. This method is faster and less expensive than dry docking. An in-water survey […]
Water injection is the practice of injecting a water and alcohol mixture into the fuel system or combustion chamber of an internal combustion engine to increase power output and reduce engine damage caused by heat. This technique has been used in fighter aircraft and racing cars since World War II and can also benefit diesel […]
Water births involve a woman sitting in warm water during labor, which can mimic the amniotic fluid and ease the transition for the baby. It can also help the mother feel more in control and relaxed. However, it is not recommended for all women, such as those with infections or preterm labor. Water births are […]
Water taxis have been used for thousands of years to transport people and goods between villages. Today, they are used in major cities for transportation, sightseeing, and private parties. Vessels are inspected by the Coast Guard and offer amenities such as restrooms and outdoor terraces. Submarine tours are also available in tropical regions. The water […]
Hard water causes problems for appliances and homes due to mineral deposits. Traditional water softening methods create waste and remove healthy minerals. Magnetic water softeners use a magnetic field to soften water without waste or loss of health benefits. The magnetic field neutralizes the minerals that create hard water. Magnetic water softeners have many advantages, […]
Hydraulic pumps move fluids with pressure to do work. Types include gear, screw, vane, radial piston, axial piston, and gerotor pumps. Thin oil is used in hydraulic systems. Hydraulic pumps are mechanical devices designed to move fluids with sufficient pressure to impart energy into the fluid body. This is a rather technical way of saying […]
Water well pumps are necessary to draw water from underground wells for use in homes and other structures. Different designs are available, including jet and submersible pumps. Clogging and priming are common issues that need to be considered in their design and installation. The pump should not exceed the power of the well and may […]
Water towers hold water supplies and maintain water pressure in municipal systems. They use gravity to pressurize pipes and can store up to a day’s worth of water. They also prevent contamination and save costs by delivering water during peak demand periods. A water tower is a structure designed to hold a water tank and […]
Water towers are structures that hold water and maintain water pressure in municipal systems. They can deliver water during blackouts and pump failures. They also help avoid negative pressures and can save costs by delivering water during peak demand periods. A water tower is a structure designed to hold a water tank and also to […]
A 12-volt water pump is ideal for RVs and small boats, powered by a car battery and able to pump fresh water from holding tanks or bilges. They are rugged and can withstand constant use, with plastic impellers that resist rust and corrosion. A 12-volt water pump is the ideal way to supply running water […]
Companies and municipalities face the challenge of disposing of wastewater in an environmentally friendly and cost-effective way. Two common methods are removing sewage from the site or creating on-site facilities to treat water. Hiring a water treatment company is also an option. Compliance with local regulations is essential. Disposal of waste water is a problem […]
Water pumping involves moving water from one area to another for various purposes such as drinking, irrigation, and wastewater treatment. Common pumps include solar, water well, electric, submersible, hand, sump, and vehicle pumps. Hand pumps are preferred in some rural areas for their hygienic benefits. Water pumping is a term used to describe the process […]
Water wheels harness the energy of moving water and have been used for millennia. They come in three types: horizontal, undershot, and overwheel, with the latter being the most efficient but also having a greater environmental impact. Moving water has a lot of energy. Just six inches (15 centimeters) of running water can wash off […]
A water treadmill is an exercise machine used underwater, with simple versions consisting of a self-powered conveyor belt and a bar for the user to hold onto. More complex versions can include a jet of water for resistance and an incline. The benefits include less pressure on joints and increased resistance. A water treadmill is […]
Water splitting is a process of breaking down water into hydrogen and oxygen. It has potential as an alternative to fossil fuels, with solar energy and chemical catalysts offering promising methods. The challenge is to develop cheap and durable electrodes. Research is increasing efficiency, but it is still more expensive than generating hydrogen-based fuels from […]
Water aerobics is a low-impact exercise that is beneficial for people with joint problems, arthritis, and soft tissue injuries. Equipment such as foam noodles, buoyancy belts, kickboards, weights, and gloves can be used to provide balance, resistance, and added intensity to the workout. Water aerobics is a popular form of exercise among people who have […]
