6) The diagram below shows the air supply ductwork for an office space. All ducts are round. The fan discharges into a plenum takeoff fitting (209). B and C are full-flow tee fittings. G and D are 90°L (R/D=1.5) elbows. E, F, and Hare top ceiling boxes that discharge into the rooms. For all fitting equivalent lengths, assume Ah/l = 0.1"/100' and diameter of 12". Use the equal friction method and Ductulator to fill in the table below. Then determine the total fan head (static plus velocity) and air horsepower that the fan must supply.
