Pipeline Pressure/Friction Loss
The form calculates the pressure or friction loss along a given length of pipeline with a specified inside diameter. Additional pressure losses can occur due to fittings, which add an extra length to the total pipeline. The pressure losses can be estimated using the fitting pressure loss calculator, which gives an equivalent pipe length to add to the overall pipeline length.

This claculator uses this formula to determine the pressure loss due to pipe friction.
