C-UNIT 13 (2) The system has been calculated to provide an average imbalance at each node of 0.010 gpm and a maximum imbalance at any node of 0.089 gpm. (3) Total pressure at each node is used in balancing the system. Maximum water velocity is 19.2 ft/sec at pipe 10. (4) Items listed in bold print on the cover sheet are automatically transferred from the calculation report. (5) Available pressure at source node 10 under full flow conditions is 82.00 psi with a flow of 29.67 gpm.
