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 0.012 gpm and a maximum
imbalance at any node of 0.140 gpm.
(3) Total pressure at each node is used in balancing the system.
Maximum water velocity is 7.5 ft/sec at pipe 2A.
(4) Items listed in bold print on the cover sheet
are automatically transferred from the calculation report.
(5) Available pressure at source node SOURCE under full flow conditions is
49.85 psi compared to the minimum required pressure of 0.00 psi.
