Tap Size vs. Turf Area Table#

This table is intended as an aid for irrigation design. The values are calculated assuming peak daily evapotranspiration rates of 0.25 inches for Kentucky Bluegrass and 0.20 inches for Turf-type Tall Fescue. For the purposes of the calculations, assume that the irrigation efficiency and tap utilization efficiency are equal to 100 percent, and the maximum time of irrigation is 8 hours. More realistically, however, this would be equivalent to irrigation and tap utilization efficiencies of 80 percent, and a maximum irrigation time of 12 hours.

These maximum discharges assume a disk-type meter. In certain cases irrigation-only taps that are 1-1/2 inches or larger, turbine meters are allowed, which have higher maximum discharge limits.
