What term describes a building system designed using calculated hydraulics rather than standard pipe schedules?

• A. Calculated system
• B. Standard system
• C. Hybrid system
• D. Variable system

Answer: (A)

Designing a building sprinkler system with calculated hydraulics means sizing piping by performing hydraulic calculations that account for the actual flow demands, pressures, and friction losses in every branch, rather than picking pipe sizes from a standard pipe schedule. This approach ensures each sprinkler head gets the required water at the correct pressure. The term for this method is a calculated system. A standard system would rely on predefined pipe sizes from schedules without running full hydraulics, a hybrid would mix methods, and a variable system isn’t the established term for this concept.
