MWscap M cap W sub s = Molecular weight of the suction gas.

To build your fixed .xls sheet, you must program these fundamental equations into your cells. Mass Balance The total discharge mass flow rate ( ) is the sum of motive ( ) and suction ( ) flow rates. md=mm+msm sub d equals m sub m plus m sub s Entrainment Ratio ( ejector design calculation xls fixed

Engineering error rate dropped from 18% to 2%. The fixed XLS allowed junior engineers to size ejectors without fear of breaking the model. Mass Balance The total discharge mass flow rate

: Online calculation resources that provide performance curves at fixed ejector geometry and design discharge pressures. and nozzle geometry.

An ejector (or eductor) uses a high-pressure motive fluid to entrain and compress a low-pressure suction fluid. Designing an efficient system requires precise calculations of mass flow rates, pressure drops, and nozzle geometry.

The diffuser must slow the mixed fluid down to recover pressure.
