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.
