because you force it into a smaller space therefore you increase the pressure

What is an advantage of a solid stream nozzle?

A solid stream nozzle provides a concentrated and powerful jet of water, which is highly effective for penetrating tough surfaces and reaching distant targets. This focused stream minimizes water dispersion, allowing for precise control during firefighting or cleaning tasks. Additionally, the solid stream reduces the risk of steam or vapor formation, enhancing safety for the operator in hazardous environments.


When would you adjust a fire hose nozzle to provide a solid stream of water?

Some of the advantages of solid streams include:The ability to propel water farther than other types of streams.Has more penetration power than other types of streams.Less prone to clogging with debris.


What is the distance of Vena-Contracta from Nozzle?

The vena contracta is typically located at a distance of approximately half the diameter of the nozzle downstream from the nozzle exit. This is the point where the fluid stream reaches its minimum cross-sectional area and maximum velocity, following the contraction caused by passing through the nozzle. The exact distance can vary depending on factors like the flow conditions and the specific geometry of the nozzle.


What does jet stand for?

a. A high-velocity fluid stream forced under pressure out of a small-diameter opening or nozzle. b. An outlet, such as a nozzle, used for emitting such a stream. c. Something emitted in or as if in a high-velocity fluid stream: "such myriad and such vivid jets of images" Henry Roth. d. A jet-propelled vehicle, especially a jet-propelled aircraft. e. A jet engine.


Which sediments would a stream carry at 5 cm?

In a stream, heavy sediments settle quickly and finer sediments stay suspended in the water and get carried down stream farther, even as the stream shrinks in size.


Is one of the effects of El Nino that the jet stream shifts farther north?

Possibly...


What is the spear and nozzle?

The spear and nozzle is a type of firefighting nozzle design that allows firefighters to control the flow of water while maximizing its reach and effectiveness. The spear is a tapered metal pipe that directs water in a concentrated stream, while the nozzle can adjust the spray pattern and pressure. This combination allows for versatility in attacking fires, whether from a distance or in close quarters. It enhances firefighting efficiency, especially in difficult or hazardous environments.

Which type of nozzle is used to fight fires in inaccessible places such as attics and basements?

The type of nozzle commonly used to fight fires in inaccessible places like attics and basements is a "smooth bore nozzle." This nozzle creates a solid stream of water that can penetrate through smoke and reach the fire more effectively. Additionally, the "fog nozzle" can also be used for its ability to create a fine mist, which aids in cooling and reducing visibility issues. Both types are valuable for tackling fires in confined or hard-to-reach spaces.


What kind of motion should you impact to the nozzle of a garden hose so that the resulting stream of water approximates a sine curve?

A periodic up-and-down motion.


What change in the stream would cause pebbles to be deposited farther offshore?

A greater volume of water would cause this.
