Need more water. Reduce or feather the panal. Intake hydrant drop: 16 - 25% drop, you can? Same amount, no more. Intake hydrant drop: 0 - 10% drop, you can? 3 like lines. Red hydrant tops = Class C Hydrant 499 GPM or lower. Orange hydrant tops = Class B Hydrant 500 - 999 GPM Green Hydrant tops = Class A Hydrant 1000 to 1499 GPM Lt Blue Hydrant tops = Class AA Hydrant 1500 GPM, or above. FL = CQ2L EP = EP = NP + FL + A + +/- Coefficients for standpipe: Department standard: 25 + lines Intake drop: Process to add lines: 1) Take Static reading on intake after hitting source. 2) Get residual reading. 3) Take Static reading, and - residual reading. 4)Times difference by 100. 5)Take that difference and divide by the static reading. Nozzle Pressure: Square root of 50 is: 7.07 Nozzle Pressure: Square root of 80 is: 8.94 Nozzle Pressure: Square root of 100 is: 10 7/8 nozzle = 150 gpm Appliance/wye/siamese = what psi? 10 psi Monitor/standpipe psi 15 psi department 25 IFSTA Fog nozzle psi = 100 psi Rule of thumb: EP for 1 1/2, and 1 3/4 preconnects = 135 psi Supplying (relay) another engine at? 25+ friction loss Q2 Friction loss: 125 gpm = 1.56 Q2 Friction loss: 150 gpm = 2.25 Q2 Friction loss: 175 gpm = 3.06 Q2 Friction loss: 225 gpm = 5.06 Q2 Friction loss: 250 gpm = 6.25 Q2 Friction loss: 275 gpm = 7.56 Q2 Friction loss: 325 gpm = 10.56 Q2 Friction loss: 350 gpm = 12.25 Q2 Friction loss: 375 gpm = 14.06 Q2 Friction loss: 425 gpm = 18.06 Q2 Friction loss: 450 gpm = 20.25 Q2 Friction loss: 475 gpm = 22.56 Determining Elevation for Structures/wildland: Structure Add 5 psi per floor - 1. +/- .5 x elevation. Hydrant drop: Formula for hydrant drop: % drop = Static - residual x 100 divide by static. Hydrant drops from intake readings: 0-10%: 3 times amount 11-15% drop: 2 times amount 16-24% drop: same amount 25+ : look elsewhere Class A Foam consentration pumping level? .1 to 3% .3 to .5 w/fog nozzles Foam percentage for Fire Attack, and Overhaul? .2 to .5% Exposer protection foam %, with standard fog nozzle?
