What is the calculated discharge pressure (DP) for Engine 8 when using 5" hose?

• A. 196 psi
• B. 200 psi
• C. 191 psi
• D. 180 psi

Answer: (A)

To determine the calculated discharge pressure (DP) for Engine 8 when using 5" hose, consider the method used to arrive at the discharge pressure value. When calculating discharge pressure, various factors such as flow rate, friction loss due to hose length and diameter, and elevation changes are taken into account. In this scenario, if 196 psi is the calculated discharge pressure for Engine 8, it would imply that the flow dynamics and hose specifications have been effectively analyzed. The 5" hose diameter facilitates a lower friction loss compared to smaller diameter hoses, allowing for a more efficient flow of water under pressure. Additionally, if this value aligns with operational charts or tables that accommodate similar equipment and hose sizes, it further validates the accuracy of the calculation. The importance of using the correct discharge pressure cannot be understated, as it ensures that the engine operates within its designed parameters, maintaining safety and effective firefighting capabilities. This calculated discharge pressure of 196 psi would support optimal flow rates necessary for firefighting operations while considering the hose size and associated factors influencing pressure loss.
