Example 6-9 Ejector Load For Steam Surface Condenser 

A surface condenser condensing the steam from a process lurbine drive operates at 1.0 in. Hg abs. The condensing load is 85,000 lbs/hr steam. What is the capacity of the ejector  

The temperature of the condensing steam at 1.0 in. Hg is 79°F (from steam-tables). 

The saturation pressure corresponds to a temperature of 79° — 7.5°F = 71.5°F, based on condenser-ejector design practice. The pressure from steam tables = 0.78 in. Hg abs. The water vapor to saturate the air going to the ejector is
