A cylindrical tank 24 inches in radius and 2 meters tall initially contains 100 gal of cane juice. A level sensor is installed in the tank which signals an alarm once 70% of the total volume of the tank has been reached. Att = 0, a cane juice containing 40% sugar is poured into the tank at a rate of 15 gpm, while the well-stirred mixture leaves at a rate of 5 gpm. Assuming that due to operator negligence, this process continued at constant rates, after how many minutes will the alarm sound? Use 1 gal = 3.785 Li.
