Scenario 48: If a nozzle is flowing at 250 GPM and the pump pressure is 150 PSI, what is the approximate friction loss per 100 feet of 2.5-inch hose, if the friction loss for two 100-foot sections is known to be 80 PSI? (This is a simplified scenario for estimation).

Question: Scenario 48: If a nozzle is flowing at 250 GPM and the pump pressure is 150 PSI, what is the approximate friction loss per 100 feet of 2.5-inch hose, if the friction loss for two 100-foot sections is known to be 80 PSI? (This is a simplified scenario for estimation).

Answer options:

• 20 PSI
• 30 PSI ✅ 40 PSI
• 50 PSI

Correct answer: 40 PSI

Explanation: If two 100-foot sections have a friction loss of 80 PSI, then one 100-foot section would have half that, which is 80 PSI / 2 = 40 PSI. The correct answer is "40 PSI". This capacity-fill scenario 48 reinforces the same competency for the firefighter-math bank and follows the certified explanation standard.
