Description
This spreadsheet calculates pressure drop for two-phase gas-liquid flow in piping using the Lockhart-Martinelli and Friedel methods. It determines flow regime, void fraction, and pressure gradient for horizontal and vertical segments. Key inputs include gas and liquid flow rates, fluid properties, pipe geometry, and inclination angle. Key outputs include flow regime, pressure drop per unit length, and total line pressure drop. Designed for process and piping engineers, EPC contractors, and plant engineers. Editable Excel format. Engineering support available — contact 3D-LABS.
