Simple calculation of nozzle throat diameter, diffuser throat diameter and condenser diameter of water vapor jet pump

Thread Content

1. Calculation of nozzle throat diameter D0 (1) In the formula, G0——working steam consumption (kg/h), G0=Gh/μ. Gh is the pumped gas volume (kg/h), μ is the ejection coefficient, which can be obtained by looking up the table. 　　P0——Working steam pressure (Pa)2, calculation of diffuser throat diameter D3 (2) where GK——air flow rate passing through the diffuser throat (kg/h) GZ——steam flow rate passing through the diffuser throat (kg/h) P4——diffuser outlet pressure (Pa)3, calculation of condenser diameter D (3) where G∑h——mixture flow rate entering the condenser (kg/h) v∑h——The specific volume of the mixture entering the condenser (m3/kg), which can be approximately replaced by the saturated water vapor specific volume found in P4. picture: Simple calculation formulas for jet pump nozzle throat diameter, diffuser throat diameter, and condenser diameter
