Ejector Design Calculation Xls - Fixed

This write-up provides a technical overview and operating instructions for a fixed-geometry Steam Jet Ejector Design Calculation

Elias found the "fixed" section of his calculation—a set of empirical constants labeled A through J that dictated the flow behavior. He realized the previous engineer had used a generic coefficient of determination ( ejector design calculation xls fixed

To generate an accurate design, the following parameters must be entered into the spreadsheet: Motive Fluid Data: Pressure ( cap P sub m ), Temperature ( cap T sub m ), and Flow Rate ( cap W sub m Suction Fluid Data: Pressure ( cap P sub s ), Temperature ( cap T sub s ), Molecular Weight ( cap M cap W ), and Flow Rate ( cap W sub s Discharge Data: Required Discharge Pressure ( cap P sub d System Constraints: Compression Ratio ( ) and Expansion Ratio ( 3.
