Does the glass tube in a fire sprinkler expand more or less than the liquid inside the tube?
The glass tube in a fire sprinkler expands less than the liquid inside the tube when exposed to heat. This difference in expansion causes the glass tube to break and activate the sprinkler system in the event of a fire.
What are 4 types of physical reaction?
Four types of physical reactions include melting (solid to liquid), freezing (liquid to solid), evaporation (liquid to gas), and condensation (gas to liquid). These reactions involve changes in the physical state of matter without changing its chemical composition.
Examples of the nine types of solution according to physical state?
Solid in solid: metal alloys. Liquid in liquid: vinegar dissolving in water. Gas in gas: air. Solid in liquid: salt dissolving in water. Liquid in solid: mercury absorbed by gold. Gas in liquid: carbon dioxide dissolving in soda. Solid in gas: smoke particles in air. Liquid in gas: water vapor in air. Gas in solid: hydrogen absorbed by palladium.
What is the NFPA Standard that relates to automatic sprinkler systems?
The NFPA standard related to automatic sprinkler systems is NFPA 13, which provides guidelines for the design, installation, and maintenance of sprinkler systems. It covers various types of sprinklers, water supplies, and system components to ensure effective fire protection.
Does the size of the hole in a spinning sprinkler in a can effect how fast the sprinkler will spin?
Yes, the size of the hole in a spinning sprinkler can affect how fast the sprinkler will spin. A larger hole will allow more water to flow out, increasing the force that drives the rotation of the sprinkler. Conversely, a smaller hole will reduce the force and may result in a slower spinning speed.
Which types of pipe use in fire sprinkler?
Black steel
Where could I research different types of sprinkler systems?
I need to add an irrigation system to my lawn. Where could I go to see different types of sprinkler systems that could fit my needs?

Does the glass tube in a fire sprinkler expand more or less than the liquid inside the tube How do you know?
Loads more The liquid expands more than the glass envelope. You know this because the mechanism is designed to open the water valve to the sprinkler head when the glass envelope shatters when the liquid ruptures it as it heats up.
What are the different types of sprinklers?
The term sprinklers typically refers to devices that discharge water for irrigation or fire control applications. Irrigation sprinkler systems can be either manual or automatic. Three common types of irrigation sprinkler heads are sprays, rotors (impact or gear drive), and multi-stream rotators. Fire sprinkler systems types include wet pipe, dry pipe, deluge, pre-action, foam water, and water spray. Common types of fire sprinkler heads are bulb, upright, pendant and side wall.
How do fire sprinkler systems put out fires?
Fire sprinklers have two major components that operate in response to a fire: the fire sprinkler heads which are connected via a series of pipes to a fire pumps. Water pressure is kept in the head by a series of valves in the pump. and is kept in the heads by little vials of colored liquid. During a fire, the liquid inside the sprinkler heads heats up and starts to expand, eventually causing the vial to burst. Water that was kept in the pipes pours out of the sprinkler heads. The water pouring out of the sprinkler heads causes the pressure in the fire pump to drop. In response, the pump kicks on and pumps more water from the municipal water supply to keep the sprinkler flowing. NOTE: this is how "wet pipe" fire sprinklers, the most common types of fire sprinklers, work. Other sprinklers (dry pipe, deluge and pre-action) are slightly different.
What sprinkler systems are the simplest types of automatic fire sprinkler system?
Automatic Sprinkler of Connecticut LLC specializes in the simplest and most cost-effective types of automatic fire sprinkler systems, wet pipe sprinklers. Wet pipe sprinklers are the most common type of sprinkler system and are very reliable. They use water from a pressurized supply line to activate the sprinklers in case of smoke or heat detection, quickly suppressing any fires while minimizing damage.
What exact type of liquid is used in fire sprinkler bulbs to explode by thermal expansion?
It depends on the temperature rating of the particular bulb, but all bulbs are filled with aproprietary glycerin liquid.
Types of sprinkler irrigation system?
Sprinkler irrigation systems fall into two major classifications: landscape and agricultural. Types of landscape irrigation systems include aboveground and underground and either of these may use manual or automatic controls and timing. Types of landscape irrigation sprinklers range all the way from hand-held nozzles to advanced valve-in-head gear drive rotors. Types of agricultural surface irrigation systems include basin, border strip, and furrow irrigation. Types of agricultural sprinkler irrigation include hand-move, side roll, traveling gun, center pivot, linear move, and solid set. Drip irrigation systems are rapidly replacing traditional landscape and agricultural sprinkler irrigation systems in select applications because of their high water efficiency.

Does the glass tube in a fire sprinkler expand more or less than the liquid inside the tube?
The glass tube in a fire sprinkler expands less than the liquid inside the tube when exposed to heat. This difference in expansion causes the glass tube to break and activate the sprinkler system in the event of a fire.
What is the liquid in a frangible - bulb fire sprinkler?
The glass bulb inside a fire sprinkler head is filled with a heat sensitive liquid (e.g., glycerine) that expands faster than the glass bulb as it gets hotter. Eventually, it expands so much that it causes the glass bulb to burst, releasing the water behind it.The different colors of liquid contained within the bulb correlate to the temperature at which the sprinkler head will activate:Orange - 135oFRed - 155oFYellow - 174oFGreen - 200oFBlue - 286oFPurple - 360oFBlack - 440OFDifferent colors are used in different environments depending on the average ambient heat in said environment. For instance, if you have a storage facility that needs to be kept at temperatures higher than 135 F, you can imagine why you wouldn't want a orange-bulbed fire sprinkler!
