When you have calculated the proportional value of
your pipeline, extend your line down from the upper
right quadrant until it intersects with the line that
represents your pipeline. When you reach the
intersection, make a 90° turn
clockwise into the lower
left quadrant. As noted previously, we are using 500
feet as our proportional value (Figure 54).
4. The lower left quadrant refers to the pumpability
of the concrete. If the concrete specifications allow
a range in slump (for example 5–6 in.), always use
the lower end to be safe. In our example, we use 5-
inch slump. Extend the line from the lower right
quadrant until it intersects with the 5-inch slump
line; then make a 90° turn
clockwise . This will lead
you back into the upper left quadrant (Figure 55)
through the pressure scale.
