Barrel Filling

Side views of four barrel figures 

Design Criteria:

• Figure 1 with 1" slot
  - Q = 100 cfm/ft² barrel top minimum
  - Duct velocity = 4,200 to 4,500 fpm
  - Entry loss = 0.25 vp + 1.78 slot vp
  - Manual Loading
• Figure 2
  - Q = 150 cfm/ft² open face area
  - Duct velocity = 4,200 to 4,500 fpm
  - Entry loss = 0.25 vp for 45° taper
• Figure 3 with feed spout and exhaust duct
  - Q = 50 cfm x drum dia (ft) for weighted lid
  - Q = 150 cfm x drum dia (ft) for loose lid
  - Duct velocity = 4,200 to 4,500 fpm
  - Entry loss = 0.25 vp
• Figure 4
  - Q = 300 - 400 cfm
  - Duct velocity = 4,200 to 4,500 fpm
  - Entry loss = 0.25 vp
