NOTES (HASS) :
(1) Calculations were performed by the HASS 8.4 computer program
under license no. 5003013219 granted by
HRS Systems, Inc.
208 Southside Square
Petersburg, TN 37144
(931) 659-9760
(2) The system has been calculated to provide an average
imbalance at each node of 0.011 gpm and a maximum
imbalance at any node of 0.066 gpm.
(3) Total pressure at each node is used in balancing the system.
Maximum water velocity is 7. 6 ft/sec at pipe 5.
(4) Items listed in bold print on the cover sheet
are automatically transferred from the calculation report.
(5) Available pressure at source node 1 under full flow conditions is
74 .75 psi compared to the minimum required pressure of 0.00 psi.
