Formula | The pressure drop in pipes is the sum of the linear pressure drop due to friction with the pipe walls and the singular pressure drop due to the bends, valves...etc... present in the pipePressure drop for straight pipesPressure drop due to piping singularitiesandTotal pressure dropΔP_{T}=ΔP_{f}+ΔP_{S} |

Nomenclature | f/2=friction factor D_{H}=Hydraulic diameter in m u_{m}=mean velocity in m/s ΔP_{f}=pressure drop due to friction in Pa L=length of pipe in m ρ=specific gravity in kg/m3 ΔH_{s}=pressure drop due to pipe singularity in m ΔP_{s}=pressure drop due to pipe singularity in Pa |
