Ejector design calculation spreadsheets typically include automated formulas to determine the entrainment ratio compression ratio physical dimensions
A professional ejector spreadsheet requires these input fields, typically separated by service type (Gas-Gas, Steam-Jet Vacuum, Liquid-Liquid). ejector design calculation xls
Suction inlet conditions and suction velocity β vs motive pressure m_s vs m_p Efficiency
Cell formatting note: Use named ranges (M_dot_m, P_m, etc.) to avoid cell reference errors. typically separated by service type (Gas-Gas
For steam ejectors, use empirical curve-fit (ESDU 85032):
Designing an efficient ejector system is a critical task in process engineering, as these devices offer a reliable, low-maintenance way to create a vacuum or pump fluids without moving parts. Using an ejector design calculation xls (Excel spreadsheet) allows engineers to rapidly iterate through various parameters like motive pressure, suction load, and compression ratios to find an optimal configuration.
