Ejector Design Calculation Xls

: Start by clearly stating what the spreadsheet does. For example, "This XLS tool streamlines the complex 1-D thermodynamic modeling required to design steam or gas ejectors, calculating critical dimensions such as the motive nozzle throat and diffuser geometry". Technical Parameters (Inputs/Outputs) : Motive Stream : Pressure ( Ppcap P sub p ), Temperature ( Tpcap T sub p ), and Mass Flow Rate ( Suction/Entrained Stream : Pressure ( Pscap P sub s ), Temperature ( Tscap T sub s ), and Molecular Weight. Calculated Results : Entrainment Ratio ( ), Throat Area ( A*cap A raised to the * power ), and Dry Air Equivalent (DAE) ratings.
