Final answer:
The question involves Physics, specifically fluid dynamics related to Torricelli's Law, at the High School level. It concerns the calculation of the volume of water remaining in a tank after some time has passed, using the provided equation that demonstrates the principles of Torricelli's theorem.
Step-by-step explanation:
The subject of the question is Physics, particularly fluid dynamics as it applies to Torricelli's Law. The grade level is most likely High School, as this concept is typically covered in introductory physics courses at this level. Torricelli's theorem states that fluid exits a tank at the same speed it would achieve if it fell freely from the fluid surface level in the tank to the point of exit with no friction involved.
To calculate the volume V of water remaining in a tank using Torricelli's Law, the equation provided is V = 5500(1 - 1/50t)². After t minutes, this equation allows us to determine how much water is left in the tank. The SI unit for flow rate is m³/s, but for practical purposes, other units like gallons and liters may be used, as is demonstrated by the volume of water in the tank which is 5500 gallons.
