Typical target I have used for fluid velocity in piping design is 7-10 ft/sec. What are the implications of higer and lower values? I realize the obvious, like friction losses and the related pump sizing, but am not sure about performance.
If a lower value is used, say 1-2 ft/sec to gain...
I am interested if anyone could lead me to an analysis of capital and operating cost comparison of air cooled vs. water cooled chillers. Further to that point, screw vs. helical, or other types of compressors.
