Friction loss essentially refers to resistance caused by fluid flowing through pumps, pipes, and fitting. That resistance results in decreased pumping pressure and decreased fluid velocity.
Friction between the adjacent fluids – higher viscosity fluids have higher losses.
Solutions for Friction Loss
1. Reduce interior surface roughness of the piping system.
2. Increase the pipe diameter of the piping system.
3. Minimize the 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.
