When considering a deck gun, what is the friction loss for the deck gun noted?

The friction loss for a deck gun is an important factor to consider because it directly affects the water flow and pressure available at the nozzle, which are critical for effective firefighting. Standard guidelines for friction loss state that a deck gun typically incurs a friction loss of around 10 psi, which is based on both the flow rate and the length of the hose connected to it.

When water flows through hoses or other fittings, it encounters resistance, and this resistance translates to friction loss. The 10 psi figure for the deck gun is generally accepted in fire service operations and serves as a baseline for operators to calculate the total pressure losses in the system.

Understanding this friction loss is key for operators as it informs decisions about pump pressures and helps ensure that the deck gun can deliver the necessary flow and pressure to effectively suppress a fire. Using the correct friction loss calculation allows for better overall management of the pump and the water supply system, contributing to operational efficiency.
