Equations for calculating required pump pressure given flowrate, xsa, length

[Dave-RR]

is there any equations that can be used for calculating required pump pressure for a horizontal running water pipe given the pipe length, cross-sectional area, required flowrate and frictional loss co-efficient??

is this possible or is more information required?
