Estimation thumb rule.

Hi All,

while reading one document reagarding Piping, they have written
"MTO for Steam Traps, Valves (for Vent and drain) can be calculated by using Thumb Rules"

I can understand that at the initial stage by keeping rake position and layout we can assume all posible rise and drops of our line and thus can estimate steam traps and vent drain.
But as written in doument, I am not aware about any thumb rule.

It will be heplful if anybody can share their views reagardsing the same.

Have a look at this website for guidance of steamtraps
