• B. 1/2 inch
• C. 3/4 inch
• D. 1 inch

Answer: (B)

The most common size for a sprinkler orifice is 1/2 inch. This size is widely used in residential and commercial fire protection systems due to its effectiveness in providing adequate water coverage for a variety of applications. A 1/2 inch orifice allows for a balanced flow of water, ensuring that enough pressure and volume are delivered to effectively suppress fires while minimizing water waste. Using a 1/2 inch orifice helps to meet the required design criteria specified in national fire protection standards. Fire sprinkler systems are designed to operate efficiently, and the 1/2 inch size is optimal for achieving the necessary discharge rates to comply with safety and regulatory standards.
