1	July 2005 Hose load and FAE review
2	Objectives Review current hose loads and appliances Review proper flows for selected hose lines Review basic friction loss factors Review basic pump operations Demonstrate pumping lines
3	Cross lays 2 on each engine Front is 200 feet Rear is 150 foot Both use 1 ¾ hose Loaded with last 75 feet in a horseshoe finish with the nozzle ending up in the middle of the load.
4	Crosslays Both use a combination fog nozzle Flows 150 GPM Works at 75 PSI Smooth bore nozzle flows 180 GPM @ 50 psi
5	Crosslays Each 100 foot section of 1 ¾ hose has a friction loss of 22 PSI when flowing 150 GPM. 10 (Q) ² 10X(1.5x1.5)=22.5 10X(1.8x1.8)=32.4
6	Crosslays Front crosslay with a fog nozzle uses a PDP of 119 (75+ 22 +22) Rear crosslay with a fog nozzle uses a PDP of 108 (75+ 22+ 11) Using the smooth bore nozzle increases FL to 32 and decreases NP to 50
7	2 ½ Minute Man / Blitz Line Driver side of rear hose bed Made up of 200 feet of 2 ½ hose Load starts with first 100 feet flat and connected to port. Next 100 feet are loaded starting with the nozzle. Keep length under 7’ for easier deployment
8	2 ½ Minute Man / Blitz Line Load uses a 1 ¼ inch smoothbore nozzle Flows 300 GPM Works at 40 PSI nozzle pressure
9	2 ½ Minute Man / Blitz Line Smooth bore nozzle flows 300 GPM at 40 PSI. (1 ¼ inch tip) 2 ½ inch hose has a friction loss of 21 PSI for each 100 foot section when flowing 300 GPM
10	2 ½ Minute Man / Blitz Line 2 (Q²) + Q 2 x (3x3) + 3 3x3=9x2=18+3 = 21 40 NP + 21 + 21= 82
11	Supply hose (5 inch) 650 feet, loaded flat Flakes should be staggered Each section is 100 feet in length – first section off is 50 foot. All couplings should be placed at the front end of the hose bed Used to provide supply from hydrant to engine or from engine to another source
12	Supply hose (5 inch) Friction loss ranges from less than 1PSI at 100 GPM up to 14 PSI for 1500 GPM Maximum PSI should not exceed 180
13	Skid load Center skid load supplied by 3 inch hose. Used for fire attack that cross lays cannot reach
14	Skid load Skid load has 600 feet of supply hose Skid load also has 100 feet of 1 ¾ hose and a combination fog nozzle
15	Skid load Skid supply load is loaded flat starting with the female coupling Usually can be loaded 3 flakes wide Stagger flakes long and short
16	Skid load Skid load has a gated wye that connects the 3 inch supply hose to the 1 ¾ finish load. The finish load is 100 feet of 1 ¾ loaded in a reverse horseshoe. Wye is in the middle, nozzle to the outside.
17	Skid loads The finish load flows 150 GPM with the fog nozzle at 75 PSI If the fog portion is removed, the flow increases to 180 GPM, but at 50 PSI
18	Skid load The initial PDP of the finish load with out any 3 inch is 107 PSI with the fog nozzle The PDP with the fog nozzle removed is 92 PSI Add 3 PSI for each 100 foot section of 3 inch supply regardless of the nozzle.
19	Leader line Similar to the skid load. Uses 2 ½ inch hose as the supply portion. Uses 1 ¾ hose for the finish load with a 15/16 smooth bore nozzle Uses a play pipe nozzle to connect the 2 ½ hose to the 1 ¾
20	Leader line Loaded with 500 feet of 2 ½ inch hose in a flat lay beginning with the female coupling.
21	Leader line The next 100 feet of 2 ½ hose is loaded in a reverse horseshoe. The play pipe nozzle is attached. 100 feet of 1 ¾ is then loaded in a reverse horseshoe and is attached to the play pipe nozzle. Remember that the horseshoes should be NO longer than 7 feet
22	Leader line If you remove the finish load, the flow will become 300 GPM, and the FL increases to ???? What will the PDP be with 300 feet of 2 ½ ????
23	High Rise Pack Located in various compartments depending on the engine company Made up of 3 -50 foot bundles of 2 ½ hose and 1-50 foot bundle of 1 ¾ hose with a smooth bore nozzle The 15/16 inch smooth bore tip will flow 180 GPM at 50 PSI
24	High Rise Pack The HRP also has a bag which has a gated wye and a flow meter. There is a short length of 3” hose also. The bag also has some small tools
25	High Rise Pack Remember that your friction loss will be based on 50 foot lengths, not 100. 1 ¾ will loose 16, and each 2 ½ will loose about 5 for each 50 foot length
26	High Rise Pack When flowing the entire HRP, you need to set your PDP to at least 115 PSI. Add 5 PSI for each floor. If you are within 100 feet of the connection, you don’t need to worry about any loss in the 3” supply hoses.
27	Master Streams Used to flow large amounts of water Deck gun has 4 tips – what are they? Set PDP to 110 PSI when mounted on the vehicle
28	Master Streams Two bases are available for using the gun on the ground. One has two 2 ½ ports, the other takes a stortz
29	Appliances Water Thief Gated wye Siamese Trimese/Manifold Each lose 10 PSI
30	Foam Operations Uses various components such as the eductor, aerator, and application nozzle Must use the dedicated fog nozzle for 95 GPM
31	Foam Operations Set pump so that there is 200 psi at the eductor. Add any friction loss between the pump and the eductor. Which crosslay is supposed to be used? WHY??
32	Specialty nozzles Distributor nozzle Used with 2 ½ or 3 inch hose Used to flow water into confined spaces Designed to flow about 250 – 300 GPM @ 50 psi
33	Specialty nozzles Cellar nozzle Used with 1 ¾ inch hose Used to flow water into confined spaces Designed to flow about 125 – 150 GPM @ 100 psi
34	Pumping basics Remember – water in, water out, throttle up Most efficient when close to the hydrant Always open and close all valves slowly Set your relief valve Get your tank filled ASAP
35	Some short cuts 1 ¾ - 22 fog, 32 smooth bore 2 ½ friction loss – Hand method, or drop 10 method 3 inch – square the flow, or double and redouble the 2 ½ loss factor 5 inch @ 1000 GPM – 6 PSI
36	Remember this….. There are only 4 initial pressures that you need to remember……. 80, 90, 110, and 120 80 – Blitz 90 – Leader 110 – Rear crosslay & Center skid 120 – Front crosslay
37	Any Questions…..
