Δpl = f ⋅ 1 2ρ v¯2 ⋅ L d pressure loss in a straight pipe section (3) (3) Δ p l = f ⋅ 1 2 ρ v ¯ 2 ⋅ L d pressure loss in a straight pipe section. The friction factor can also be calculated mathematically based on the geometry of the pipe, as will be shown later. Note that this formula only applies to straight pipe sections.
