Is the pressure drop formula the same for horizontal and vertical pipelines? If not, how do we calculate the pressure drop of vertical pipelines?

The procedure depends on the type of setup, i.e., once-thru, recirculating, etc. Two-phase flow may be involved. The Process Engineer draws a circle around the proper area and performs a heat and material balance. With those data, the pressure profile can be determined using the available piping pressure drop formulas, curves, or programs.
