Example:
PR = (35 ml X 3.66) / (11 minutes X 16.5 sq.in.) = 128.1 / 181.5 =
.71 in/hr
Where the average measurement was 35 ml, the test took 11
minutes and the catch can throat size is 16.5 square inches.
Efficiency = Avg. of Low quarter catchments / Avg. of all
catchments * 100
Where:
Avg. of low quarter = the average of the
lowest 25% catchments
Avg. of all catchments = average of all
catchments
Example:
Efficiency = 19 ml / 35 ml * 100 = 54.3% efficiency
Where 19 ml is the average of the lowest 25% of all the
catchments and 35 is the average of all the catchments.
Process 4: Sprinkler Type Default
1.
If all of the first three processes are not possible, then set the
