Exercise: Water Treatment Design

Scenario: You are designing a small water treatment plant for a community. You need a holding tank to store treated water before distribution. The tank will need to hold a total of 10,000 liters of water.

Task:

  1. Convert 10,000 liters into cubic centimeters (cc).
  2. If the tank is cylindrical with a diameter of 4 meters, calculate the height of the tank.

Hint:

  • 1 liter = 1000 cubic centimeters (cc)
  • Volume of a cylinder = π * (radius)^2 * height

Exercice Correction

1. **Conversion:** * 10,000 liters * 1000 cc/liter = 10,000,000 cc 2. **Tank Height:** * Diameter = 4 meters, so radius = 2 meters * Volume = π * (2m)^2 * height = 10,000,000 cc * 10,000,000 cc = 10 m^3 (since 1 m^3 = 1,000,000 cc) * Height = 10 m^3 / (π * (2m)^2) = 10 / (4π) m ≈ 0.8 m Therefore, the height of the tank should be approximately 0.8 meters (or 80 centimeters).
