This webinar will begin with a brief review of the two most common design approaches—area/density and specific application. The formulas associated with each approach will be covered including those for determining sprinkler flow, pressure, and K-factors. The interaction between the formulas will be demonstrated along with how to determine the most efficient system performance including sprinkler type, area of coverage, and orifice size (K-factor). Participants will learn how to use the Hazen-Williams formula along with the impact on hydraulics from pipe type, size, and layout. Formulas for determining equivalent lengths for pipe fittings will also be examined. (Note: Participants should have a copy of NFPA 13 and a calculator with exponent functions available to get the most benefit from this course.)
Learning Objectives:
• Use the formulas for determining sprinkler flow, pressure, and K-factors
• Understand the relationship between C-Values, pipe type, and system type when using the Hazen-Williams formula
• Use the Hazen-Williams formula to calculate friction loss
• Use the formulas for determining fitting equivalent lengths
