## Pipe Sizing

Rearrange the continuity equation Q = A x V to solve for the minimum cross-sectional area, then back-calculate the diameter.

**D = 2 x sqrt( Q / (V x pi) )**

Always round up to the next standard pipe size available from your supplier.

Ejemplo Resuelto

Need 20 GPM at a maximum velocity of 6 ft/s.

  1. Q = 20 / 448.831 = 0.04456 cu ft/s
  2. A = 0.04456 / 6 = 0.007427 sq ft
  3. D = 2 x sqrt(0.007427 / pi) x 12 = 1.17 in
  4. Choose the next standard size: 1-1/4 inch pipe.
