SECTION 21 13 00.00 40 Page 5 on the drawings. Software that uses k-factors for typical branch lines is not permitted. Calculations shall be based on the water supply data measured at the site (or on the contract drawings when permitted by the Government) to substantiate that the design area used in the calculations is the most demanding hydraulically. Water supply curves and system requirements shall be plotted on semi-logarithmic graph paper so as to present a summary of the complete hydraulic calculation. Provide a summary sheet listing sprinklers in the design area and their respective hydraulic reference points, elevations, actual discharge pressures and actual flows.

Elevations of hydraulic reference points (nodes) shall be indicated.

Documentation shall identify each pipe individually and the nodes connected thereto. Indicate the diameter, length, flow, velocity, friction loss, number and type of fittings, total friction loss in the pipe, equivalent pipe length, and Hazen-Williams coefficient for each pipe. For gridded systems, calculations shall show peaking of demand area friction loss to verify that the hydraulically most demanding area is being used.

Also for gridded systems, a flow diagram indicating the quantity and direction of flows shall be included. A drawing showing hydraulic reference points (nodes) and pipe designations used in the calculations shall be included and shall be independent of shop drawings.

1.5.2 Sprinkler Coverage

Sprinklers shall be uniformly spaced except where interrupted by walls and obstructions, and to coordinate with other devices and equipment on and in the ceiling. Sprinklers shall provide coverage throughout 100 percent of the building.
