In Excel: =0.65 * (B2/B4)^(-0.55) * (2*B4/B4)^(-1.2) Ejector Calculation Excel

A professional engineering spreadsheet is typically organized into logical sections: | Feature | Excel Ejector Tool | Commercial (e

Analytical solutions are rare. Most designs rely on (like constant-pressure or constant-area mixing) combined with empirical coefficients derived from decades of experimental data. The primary goal of an ejector spreadsheet is

For a given geometry and operating pressures, there is a maximum R.

The primary goal of an ejector spreadsheet is to calculate the Entrainment Ratio ( , which is the ratio of entrained mass flow rate ( ) to motive mass flow rate ( ScienceDirect.com Entrainment Ratio ( Compression Ratio ( Motive Steam Flow (Choked): (Heat Exchanger Institute formula) cap C sub d = Nozzle discharge coefficient cap D sub n = Nozzle throat diameter (inches) cap P sub s = Motive pressure (psia) cap V sub g = Specific volume ( 2. Design Parameters for Excel Setup

The process starts by defining the physical equations required to model ejector performance. For steam ejectors, this typically involves semi-empirical correlations for the —the ratio of entrained mass flow to motive steam flow. Motive Stream : High-pressure steam used to create a vacuum.
