Dulquer Salmaan (IPA: [d̪ulkʰɐr salmaːn]; born 28 July 1983) is an Indian actor, playback singer and film producer who predominantly works in Malayalam, Tamil, Telugu and Hindi films. He graduated with a bachelor's degree in business management from Purdue University and worked as a business manager in Dubai before pursuing a career in acting.

The most common measure of DU is the low quarter DU expressed as DUlq, which is a measure of the average of the lowest quarter of samples, divided by the average of all samples expressed as percentage. The higher the DUlq, the more uniform the coverage of the area measured.

One of the current Turf and Landscape Best Management Practices published by the Irrigation Association states that the lower-quarter distribution uniformity (DULQ) should be a minimum of 55% for pop-up spray heads.

Various methods exist to determine the DU of an irrigation system. The method widely used in irrigation auditing is the Low Quarter Distribution Uniformity Method (DULQ). This method can be calculated as follows:

Distribution uniformity of lower quarter (DULQ). The ratio of the average of the lowest one-fourth of measurements of irrigation water to the average of all measurements captured by collection devices, expressed as a dimensionless number with two decimal places.

Rating of Lower Quarter Distribution Uniformity (DULQ) for Sprinkler Zones . One item that jumps out to users of the BMPs is that minimal acceptable performance for spray heads of 55% falls in the “Good” category while rotor and impacts heads are in the “Very Good” category with 70% as the acceptable minimal performance.

From the tests on residential irrigation systems, the average low quarter distribution uniformity sDUlqd value was calculated as 0.45. Rotary sprinklers resulted in significantly higher DUlq compared to fixed pattern spray heads with 0.49 compared to 0.41, respectively.
