pumper in scdf use pressure meh? i tot they use centrifugal pumps...Originally posted by MoonLightAffairs:another thing to point out is SCDF never do enough boundary cooling and like the fire engine don't have enough pressure in pumping water. Never check was the fire engine connected to the fire hydrant or not. but the amount of water they used was not enough!!!
I thought you were talking about their mobile pack kind. Cause I've went for training and taught to use that. The pump shoot short burst of water spreaded to try to contain oxygen.Originally posted by MoonLightAffairs:i mean the pressure of the fire engine pump. how to cut off the oxygen supply of the fire when its a shop on fire??? this is not a ship on fire, ship have diff compartments. you can seal the compartment by juz closing the water tight doors to it and spray water outside to do the boundary cooling. then u let the fire die off by itself after the fire consume all the oxygen within the compartment. as for the SCDF they can gain access by breaking down the gate with their sofiscated equipements and getting ready 2 hose, one to create the water wall to protect the fire fighters from the heat and the other one fight fire.
bro photo seeker, fire break out due to 3 factors. heat, fuel and air. water is use to remove the heat from the enviroment in order to extinguish the fire, not to cut off the oxygen. shooting water continuously is use to cool off the heat. hope u r not mislead by some other advertisments or misleading informations from the internet.
fire engine pump no pressure one what. 2400litres of water. if need more take from hydrant. pump is use centrifugal pump. no pressure at all right?Originally posted by MoonLightAffairs:i mean the pressure of the fire engine pump. how to cut off the oxygen supply of the fire when its a shop on fire??? this is not a ship on fire, ship have diff compartments. you can seal the compartment by juz closing the water tight doors to it and spray water outside to do the boundary cooling. then u let the fire die off by itself after the fire consume all the oxygen within the compartment. as for the SCDF they can gain access by breaking down the gate with their sofiscated equipements and getting ready 2 hose, one to create the water wall to protect the fire fighters from the heat and the other one fight fire.

thats y i said spray water outside the compartment which is on fire to cool down the heat (boundary cooling) and of cos not to open the compartment till its cool down. it will take a long time to make sure, but its worth the wait as it will save the ship. at the same time must pump the water out at the same time. if not the ship on fire will sink due to instability! looks like got bro like wolfo here know more about fire fighting than our SCDF.Originally posted by wolfo:fire engine pump no pressure one what. 2400litres of water. if need more take from hydrant. pump is use centrifugal pump. no pressure at all right?
for the ship fire, if you seal the compartment and let the fire die inside by smothering, the heat will still be trapped inside mah. then when you open the door, will have backdraft due to the sudden introduction of oxygen mah. no meh?
