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: 1 <br /> Number of active runouts: 1 <br /> Total runout outlet airflow: 850 <br /> Main trunk airflow: 850 <br /> Largest trunk diameter: 15.3 RMT•100 <br /> Largest runout diameter: 15.3 RR-100 <br /> Small•sttrunkdiameter: 15.3 RMT-100 <br /> Smallest runout diameter: 15.3 RR•100 <br /> Runout maximum cumulative static pressure loss: 0.016 RR-100 <br /> Return loss added to supply: 0.043 <br /> Total effective length of return(tt): 77.6 RR-100 <br /> System duct surface area(Scenario 4): 18.7 Exposed in Space (Linked to duct load) <br /> Total system duct surface area: 18.7 <br /> Notes <br /> Rhvac is an ACCA approved Manual J and Manual D computer program. <br /> Calculatlons are performed per ACCA Manual J Bth Edition,Version 2,and ACCA Manual D. <br /> All computed results are estimates at building use and weather may vary. <br /> Be sure to select a unit that meets both censible and latent loads according to the manufacturer's pertormance data at your design conditions. <br /> Monday,November 04,2013,11:20 AM <br />
