Design Procedure Using Sarco Chart

= latent heat of evaporation of steam at flash pressure, Btu/lb 

Establish upstream or steam pressure from which condensate is being produced and discharged into a return line through steam traps, or equivalent, psig. 

Establish the steam condensate load or rate in lbs/hr flow. 

Establish the pressure of the condensate return line, psig. 

The method is based on an allowable 5,000 ft/min velocity in the return line (mixture).
