Calculate the capacity of the tank

    1. The problem statement, all variables and given/known data
    Calculate the capacity of the tank.

    Capacity of the tank when filled to its maximum height in pounds and gallons

    Maximum height =


    Pounds: ______ gallons*8.34 pounds/gallon*.84 = ______ pounds(note the units again)

    Calculate the pounds/square foot and pounds/square inch pressure on the bottom of the tank when it is 8’4” full of a hydrocarbon with a specific gravity of .84.

    Since we have the weight of a cubic foot of the material (8.34 pounds/gallon * 7.481 gallons/cu ft * .84 = 52.41 pounds/cu ft) it is easy to get the pounds/square foot: 52.41 pounds/ft3 * 8.333 ft =____

    (Note the units again.)

    2. Relevant equations

    3. The attempt at a solution
    Maximum height = 95% which = 95 divide by 100 times 20 = 19

    Gallons are pie which is 3.1416 times (14.167)2 times 19 = 11980.067

    One cubic foot = 7.481 so you take 7.481 times 11980.067 = 89622.88

    Pounds would be 89622.88 times 8.34 times .84 = 627862.08
