For supply,they are at the exit. The cumulative static � <br /> pressure loss value for a return trunk is with respect to the entry point of the return runout upstream with the highest static pressure available. Total <br /> and cumulative static pressure loss values for the supply main trunk include any device pressure losses entered,and the cumulative may.also � <br /> include the total static pressure loss of the return side. <br /> Summary -- , ---- -- --- —�� <br /> Number of active trunks: 3 , --- -- T— -----'� <br /> Number of active runouts: g � <br /> r <br /> Total runout outlet airflow: 601 � I <br /> Main trunk airflow: gp� 1 <br /> Largest trunk diameter: 12.4 SMT-100 � <br /> I <br /> Largest runout diameter: 7 SR=100 i <br /> Smallest trunk diameter: 9 ST-120 <br />� Smallest runout diameter: 4 SRI110 ' <br /> i <br /> i. <br /> Supply fan external static pressure: 0.382 � <br />, Supply fan device pressure losses: 0.160 , � <br />� Supply fan static pressure available: 0.222 i � <br /> Runout m ' � <br /> aximum cumulative static pressure loss: 0.382 5R-150 � <br /> Return loss added to supply: 0.050 � ; <br /> Total effective length of return(ft.): 60.2 RR=100 I <br /> Total effective length of supply(ft.): 90.1 SR-'760 � <br /> Overall otal effective length(ft.): 150.3 RR-100 to SR-150 i <br /> Design overall friction rate per 100 ft.: 0.748 (Available SP x 100!TEL) � <br /> i <br /> System duct surface area(Scenario 7): 141.2 Hot Vented Attic (Linked to duct load) � <br /> System duct surface area(Scenario 4): 23 Exqosed in Space (Linked to duct load) { <br /> Total system duct surface area: 164.2 � <br /> I <br /> I <br /> i <br />' I <br /> � <br /> i <br /> ---------- ----------------=-------- —' <br /> Thursday,May O8,2014,11:01 AM <br />
