Ejector Design Calculation Xls Fixed Jun 2026

Must be higher than the discharge pressure.

If your ejector spreadsheet still fails after these fixes, consider rebuilding it from a (e.g., ASME PTC 12.2 for steam ejectors). Excel is a tool – but the physics of choking, shocks, and mixing must be respected first. ejector design calculation xls fixed

Cr=PcPecap C r equals the fraction with numerator cap P sub c and denominator cap P sub e end-fraction Pccap P sub c = Pressure of exiting vapor ( kPak cap P a Correlation for Choked Flow Must be higher than the discharge pressure

Excel is great for preliminary sizing and parametric studies. However, for , condensing ejectors , or off-design performance maps , dedicated tools are better: Cr=PcPecap C r equals the fraction with numerator

The XLS calculates the dimensions of the diffuser, where the high-velocity mix converts back into pressure. Troubleshooting Common "Fixed" XLS Issues
