notes:
*s.p.s. copper and brass pipe.
No allowance has been made for age, dierence in diameter, or any abnormal condition of the interior surface. Any factor of safety must be estimated from the local
conditions and the requirements of each particular installation. It is recommended that for most commercial design purposes a safety factor of 15 to 20% he added to
the values in the tables.
