WebThe formula most generally used is the Christiansen coefficient of uniformity (Cu) (1), which is calculated by the following equation: Cu - 100 (1.0 where x is the deviation of the individual observations from the mean value, m, and n is the number of observations. A uniformity coefficient of 100 WebUniformity Coefficient (Cu) The uniformity coefficient (Cu) is defined as the ratio of D60 to D10. A value of Cu greater than 4 to 6 classifies the soil as well graded. When Cu is less than 4, it is classified as poorly graded …
Sprinkler irrigation uniformity: Impact on the crop yield and …
Websuch as percentage for Christiansen’s uniformity coefficient and distribution uniformity coefficient for sprinkler irrigation systems in the study area were estimated as 94% and 93% respectively. Over all uniformity of sprinkler irrigation system was in the recommended level. Hence there is potential for the adoption of sprinkler irrigation ... WebAs a measure of uniformity of rainfall distribution over the surface, the Christiansen’s uniformity coefficient was used. For surface widths ranging from 0,1 to 1 m, the Christiansen’s coefficient varies from 0,8 to 0,9 for the oscillating nozzles, while for the non-oscillating nozzle it has a value of 0,46. free pc games for 4gb ram
