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 e return runout upstream with the highest static pressure available. Total <br /> and cumulative static pressure loss values for the supply main trunk incl de 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 airtlow: 850 <br /> Main trunk airtlow: 850 <br /> Largest trunk diameter: • 15.3 T-100 <br /> Largest runout diameter: 15.3 R-100 <br /> Smallest trunk diameter: 15.3 MT-100 <br /> Smallest runout diatneter: 15.3 R-100 <br /> Runout maximum cumulative static pressure loss: 0.016 R-100 <br /> Return loss added to supply: 0.043 <br /> Total effective length of return(ft.): 77.6 R-100 <br /> System duct surface area(Scenario 4): 18.7 posed in Space (Linked to duct load) <br /> Total system duct surface a�ea: 18.7 <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 estlmates as building use and weather may va . <br /> Be sure to select a unit that meets both sensible and latent loads accordi g to the manufacturer's performance data at your design conditions. <br /> Thursday,May 08,_2014,1:18 PM <br />
