Design of Pneumatic Conveying System
From David Mills 'Pneumatic conveying system design guide' the solid loading ratio (ɸ) is 0.5. Therefore, ṁ = ρ × A × v = 8000 Kg/hr = 2.2 Kg/s Were ρ is the density of the mixture, A is the area of cross-section of the pipe and v is the velocity of discharge. By considering the solid loading ratio ṁ becomes.
