Pipeline Pressure Loss

The first form calculates the pressure or friction loss along a given length of pipeline with a specified inside diameter. The second form calculates the minimum pipe size to limit pressure loss to a specified value.

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.
