How can friction loss be overcome or reduced?

Solutions for Friction Loss

  1. Reduce interior surface roughness of the piping system.
  2. Increase pipe diameter of the piping system.
  3. Minimize length of piping system.
  4. Minimize the number of elbows, tees, valves, fittings, and other obstructions in the piping system; replace 90 degree turns with gentle bends.
