Values may vary by 0.1 psi due to display rounding. *** Device pressure loss (gain in the case of pumps) is calculated from the device’s curve. If the device curve is printed with this report, it will appear below. The length of the device as shown in the table above comes from the CAD drawing. The friction loss per unit of length is calculated based upon the length and the curve-based loss/gain value. Internal ID and C Factor values are irrelevant as the device is not represented as an addition to any pipe, but is an individual item whose loss/gain is based solely on the curve data. * Maximum Velocity of 17.65 ft/s occurs in the following pipe(s): (083-006) Date 9/8/2020 Page 8Copyright © 2002-2012 Tyco Fire Protection Products File: C:\Users\gorilla\Desktop\20-221 431 4-Plex - Rexburg\20-221 FP.dwg Device GraphsJob : 431 4-PLEX Date 9/8/2020 Page 9Copyright © 2002-2012 Tyco Fire Protection Products File: C:\Users\gorilla\Desktop\20-221 431 4-Plex - Rexburg\20-221 FP.dwg Device GraphsJob : 431 4-PLEX Date 9/8/2020 Page 10Copyright © 2002-2012 Tyco Fire Protection Products File: C:\Users\gorilla\Desktop\20-221 431 4-Plex - Rexburg\20-221 FP.dwg
