Where single values appear in the velocity tables, these may
be considered safe for water, steam, air or gas. In the shorter
insertion lengths, consideration is given to the velocity pressure
effect of water flowing at higher velocities. The values in
parentheses, therefore, represent safe values for water flow,
while the unbracketed values may be used for steam, air, gas
and similar density fluids.
