if i have a tank of fuel and i want 1

[mostafashdeed]

if i have a tank of fuel and i want to design cooling system for it i get water flow rate from equation Q= Area*Factor
Factor is 0.1 gpm/ft.sqr and Area is Area total = shell area + roof area ? is that right ?

Depends. What type of tank - shop fabricated or field erected? Is it open floating roof? What is the fuel - flammable liquid, combustible liquid, LP-Gas, LNG?

Right for what? Is the tank cooled with water? It is not stated. If so, where does the 0.1 gpm/ft.sqr come from?
Too vague. Please provide logic and basis of design. Design tank temp? Design water temp? Design air temp? Maximum leaving water temp? RH of air? What is the fuel? Fuel Specific heat? Volume and weight of fuel?

Is this question relating to fire fighting efforts so as to control overheating of nearby tanks in the proximity of a fire scene?

 

[mostafashdeed]

stookeyfpe yes but where can i find such tables ?

 

[mostafashdeed]

trashcanman' yes i use water for cooling the the tank i cant find a source for 0.1 gpm/ft2 i know that min density is 0.15 according to nfpa but at work they use 0.1 so i wanted to make sure

 

[mostafashdeed]

chicopee yes water is used for cooling to make sure tank does not affect other tasnks

Seek a registered or licensed Fire Protection Engineer. This is an internet forum, not a on line design community so you can take my knowledge and bill it to your client.
