Ejector Design Calculation Xls Exclusive -

Sheet: "Results"

A standard engineering spreadsheet for ejectors follows these sequential steps: : Motive Pressure ( Ppcap P sub p ) : High-pressure steam or fluid entering the nozzle. Suction Pressure ( Pecap P sub e ) : Low-pressure entrained vapor. Discharge/Exit Pressure ( Pccap P sub c ) : Pressure at the condenser or outlet. Calculate Ratios : Expansion Ratio ( Ercap E sub r = ) : Determines how much the motive fluid can expand. Compression Ratio ( Crcap C sub r = ejector design calculation xls

Using momentum balance (implemented in Solver), find that predicted ṁ_s = 195 kg/h → close to 200. Slightly adjust ARM to 12.8. ejector design calculation xls
