Identification, wall thickness and weights are extracted from ANSI B36.10 and B36 19. The notations
STD, XS. and XXS indicate Standard, Extra Strong, and Double Extra Strong pipe respectively.
For a turbulent flow situation, the friction factor number of 22,000. The friction factor may be
(f) may be calculated from the equation: determined on the left side of the chart. For the
example just presented, the friction factor would
be 0.025:
Friction curves, presented in Figure 11-6, may
be used to simplify the calculations. On the left
side of the chart, locate the 6-inch, Schedule 80 The length of pipe connected to the pump must
value. Follow this value horizontally until the line now be determined. Valves, elbows, tees, and
veers upward; then follow the trend between the swages create more pressure loss, or head loss,
lines labeled "inside diameter." This trend line will than a straight pipe. The equivalent lengths of
intersect the vertical line representing a Reynolds these items are presented in Table 11-1. For
