Question

The minimum satisfactory value of uniformity coefficient under normal condition of pressure and wind velocity in spinkler is

• A. 75% - 80%
• B. 80% - 85%
• C. 85% - 90%
• D. 90% - 95%

Hint:

Christiansen's Uniformity Coefficient is calculated as:
\( C_u = 100 \left( 1 - \frac{\sum |x - \bar{x}|}{n \cdot \bar{x}} \right) \).
An acceptable agricultural standard is \( C_u \ge 85\% \).
