What is the coefficient for a 2 ½" hose?

The coefficient for a 2 ½" hose is 1.43. This value is significant as it represents the friction loss per 100 feet of hose at a given flow rate. In firefighting and emergency response situations, understanding the friction loss associated with different hose sizes is crucial for determining the appropriate water pressure needed to effectively combat fires.

For a 2 ½" hose, the coefficient of 1.43 is derived from calculations that account for factors such as the diameter of the hose and the volume of water flowing through it. This coefficient helps firefighters calculate how much pressure they need to apply at the pump to ensure that adequate water reaches the nozzle under operational conditions.

Having this knowledge is essential for Driver Engineers and fire personnel as it aids in ensuring efficient water delivery and effective firefighting strategies. Accurate calculations using the correct coefficient directly impact the safety of personnel and the effectiveness of firefighting efforts. Understanding these coefficients also allows for better planning and resource management during an incident response.
