Slug Force Calculation Spreadsheet

This is a simple Slug Force calculation for two phase flow. You can fill in your number on the grey box and the output will be shown down below.

The force normally will be input into CAESAR II Piping Stress Analysis calculation to see what the impact of the force into piping system and pipe support.

The formula is well known among the engineer working in EPC Company, and was taken from one of project experience I am working with in London.
