: This is the mass flow rate of entrained vapor divided by the mass flow rate of motive steam. Equations differ based on flow type: Choked Flow (
) used to calculate mass flow rates of motive steam versus entrained vapor, along with area ratios for the nozzle throat and outlet. Key Design Parameters ejector design calculation xls
Create a on a separate sheet:
A standard calculation sheet is generally organized into the following sections: Input Parameters Motive Fluid : This is the mass flow rate of
The most vital performance metric is the entrainment ratio, defined as the mass flow rate of entrained vapor ( ) divided by the mass flow rate of motive steam ( ejector design calculation xls
