A Campbell's Soup can is 6 inches tall and has a radius of 2.5 inches
Putting out a fire with this tank.
It is estimated that a 25 cubic metre tank can hold 6,604 gallons of water.

Working off an assumed average building size:
"A structure 60' x 60' would figure to be 3600 square feet. 3600 divided
by 3 = 1200 gpm. We would need an estimated 1200 gallons per minute of
water flowing to extinguish this size area."

These numbers tell us that the tank would be able to provide continuous water for 5 min and 30 seconds. Accordinly, I would say that yes, the Campbell Soup can may have enough water to put out an smaller sized fire, but it would take more than 5 minutes to put out a full house fire. So, it really depends on the size of the fire.
Good research and calculation/ estimation, Taha -- except that I am somewhat taller than you estimated, and I actually have a size M bike frame. So that estimation has thrown off your tank size as it's more than 1.5 m high. No problem for the purposes of this problem-solving though, as it just highlights the effects of our assumed measurements! Interesting extension too, though you haven't answered the question about whether the tank should hold enough water to put out a typical house fire. Please add an **EDIT with this last bit of the question to raise this mark from a 1.5 to a 2!
ReplyDeleteThanks for the amendment and the thinking that went into it, Taha. Good work!
