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?
