• 10 per hundred ft at 100 PSI
• 25 per hundred ft at 150 PSI
• 40 per hundred ft at 200 PSI
2. 2 1/2 Hose Friction Loss Calculation
• 150 to <350 GPM
• Subract 100 and drop the last digit
• 300 GPM=20 PSI per hundred ft

• >350 GPM
• divide to get below 350
• as above
• multiply by square of divider

• from 300 to 800 GPM (2-12 PSI)
• 900=15
• 1000=20
• 1100=25
• 1250=31
• 1500=45
4. 5 inch Host Friction Loss (per 100')
• 0 if below 600 GPM
• 600=2
• 800=3
• 900=4
• 1000=5
• 1250=8
• 1500=11
