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 t e return runout upstream with the highest static pressure available. Total <br /> and cumulative static pressure loss values for the supply main trunk inclu e any device pressure losses entered,and the cumulative may also <br /> include the total static pressure loss of the return side. <br /> Summa <br /> Number of active trunks: 1 <br /> Number of active runouts: 1 <br /> Total runout outlet airflow: 600 <br /> Main trunk airflow: 600 <br /> Largest trunk diameter: 12.4 R T-100 <br /> Largest runout diameter: 12.4 R -100 <br /> Smaliest trunk diameter: 12.4 R T-100 <br /> Smallest runout diameter: 12.4 R -100 <br /> Runout maximum cumulative static pressure loss: 0.018 R -100 <br /> Return loss added to supply: 0.050 <br /> Total effective length of return(ft.): 60.2 R -100 <br /> System duct surface area(Scenario 4): 15.3 posed in Space (Linked to duct load) <br /> Total system duct surface area: 15.3 <br /> Notes <br /> Rhvac is an ACCA approved Manual J and Manual D computer program. <br /> Calculations are pertormed per ACCA Manual J 8th Edition,Version 2,an ACCA Manual D. <br /> All computed results are estimates as building use and weather may vary. <br /> Be sure to select a unit that meets both sensible and latent loads accordin to the manufacturer's performance data at your design conditions. <br /> Thursday,May 08,2014,11:01 AM <br />
