This Excel spreadsheet helps you calculate the two-phase pressure drop in a pipe. It has several stages
- First the pressure drops of the individual phases are calculated assuming that each phase is alone in the pipe (i.e. separated flow).
- Then, the Lockhart-Martinelli parameter is calculated.
- Finally, the Chisholm (1967) correlation is used to calculate the total pressure drop.
