If a tank measures 2 feet by 4 feet and holds 1,600 pounds of water, what is the water pressure at the bottom of the tank?

If a tank measures 2 feet by 4 feet and holds 1,600 pounds of water, what is the water pressure at the bottom of the tank?

• A. 100 lb/ft^2
• B. 150 lb/ft^2
• C. 200 lb/ft^2
• D. 250 lb/ft^2

Answer: (C)

To determine the water pressure at the bottom of the tank, we can use the formula for hydrostatic pressure, which is given by the equation: Pressure (P) = Weight of the water (W) / Area (A) In this case, the weight of the water in the tank is stated as 1,600 pounds. To calculate the area of the base of the tank, we multiply the length by the width. The tank measures 2 feet by 4 feet, so the area of the base is: Area = Length × Width = 2 ft × 4 ft = 8 ft² Now, substituting the values into the pressure formula: Pressure = 1,600 lb / 8 ft² = 200 lb/ft² This calculation shows that the water pressure at the bottom of the tank is 200 pounds per square foot. This is why the chosen answer is accurate.
