## ducting size calculation for pneumatic system

• #### Dense phase pneumatic conveying systems calculation / design

The following calculation can then be performed : Q air = 67*1/2.2 = 30.5 m 3 /h U pickup = 30.5/ (π*0.06 2 /4) / 3600 = 3 m/s m air = 67*1.2 = 80 kg/h τ = 2000/80 = 25 The material flow and air relative to the pipe section are conserved through scale up. For the example D …

Sizing Ducts Sizes of ducts are then given by the continuity equation like: A = q / v (1) where A = duct cross sectional area (m2) q = air flow rate (m3/s) v= air speed (m/s) Alternatively in Imperial units Ai = 144 qi / vi (1b) where A = duct cross sectional area (sq.in.) q = air flow rate (cfm) v= air speed (fpm) Frictional Pressure Loss

Hence it is imperative to find the CFM of each room before deciding the size of ducts to be installed. CFM calculation requires the size of your HVAC unit in tons to be multiplied by 400 (the average output of an HVAC unit). The total must then be divided by the square footage of your house. d.
