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.
