0.73
0.61

Question 3
How is Christiansen's Coefficient of Uniformity (CU) different from DUlq?
CU is based on average deviation of all readings from the mean; DUlq focuses only on the lowest 25% of readings
CU measures precipitation rate; DUlq measures distribution
CU applies only to drip systems; DUlq applies to spray systems
CU and DUlq are mathematically identical formulas with different names
Question 4
What is the formula for precipitation rate (PR) in inches per hour using head flow rate, head spacing, and lateral spacing?
PR = 96.3 × Q / (S × L)
PR = Q × 96.3 / (S + L)
PR = 96.3 / (Q × S × L)
PR = Q / (96.3 × S × L)
