SECTION FOUR CHAPTER 3 Automatic Sprinkler System Calculations Russell P. Fleming Introduction Types of Sprinkler Systems Applications Where Water Is Appropriate Automatic sprinkler systems are considered to be the most effective and economical way to apply water to Water is the most commonly used fire extinguishing suppress a fire. There are four basic types of sprinkler agent, mainly due to the fact that it is widely available systems: and inexpensive. It also has very desirable fire extin- 1. A wet pipe system is by far the most common type of guishing characteristics such as a high specific heat and sprinkler system. It consists of a network of piping high latent heat of vaporization. A single gallon of water containing water under pressure. Automatic sprinklers can absorb 9280 Btus (2586.5 kJ) of heat as it increases are connected to the piping such that each sprinkler from a 70ÜF (21ÜC) room temperature to become steam at protects an assigned building area. The application of 212ÜF (100ÜC).
