Calculating the Required Area

The basic formula for kalkulating railin garden area is:

11; FLT: 0 AF3; Required Area = (Impervioos Area Reaci Renof Coefisien) / Infiltration Rate 1; FLT: 1 MIL33D; IS333;

  • Pertama; FLT: 0 = 33; Runoff Coefisien = = 1; FLT: 1 = 3;: Represents that e pretignane of rainfall t becomees runof (typically 0.75-0.95).
