What does 'series' equal in relation to firefighting equipment?

In the context of firefighting equipment, the term 'series' primarily refers to the relationship between pressure levels in a system. When components such as pumps or hoses are arranged in series, the pressure in the system is additive. This means that the overall pressure achieved at the discharge point can be greater than that of individual components used separately. In firefighting, understanding how to manage and utilize pressure effectively is critical for ensuring that water is delivered efficiently and effectively to extinguish fires.

While volume, weight, and temperature are relevant factors in firefighting operations, they do not specifically relate to the concept of 'series' in the same way pressure does. Volume may refer to the amount of water available or needed, weight concerns the mass of equipment and water, and temperature relates to the heat of the environment and materials involved. However, these elements interact with pressure but do not define the term 'series' within firefighting contexts. Thus, understanding that 'series' pertains to pressure is fundamental for optimizing firefighting efforts and equipment operation.
