Notes: 1. Flow rate is in g/s at initial saturation pressure of 25 and 85 kPa (gage). Flow is based on Moody friction factor, where the flow of condensate does not inhibit the flow of steam. 2. The flow rates at 25 kPa cover saturated pressure from 7 to 41 kPa, and the rates at 85 kPa cover saturated pressure from 53 to 110 kPa with an error not exceeding 8 %. 3. the steam velocities corresponding to the flow rates given in this table can be ound from Figures 10 and 11.
