2f) Transport process of a stucco gypsum suspension during production of architectural plates [2.11]
ОглавлениеSize of the plates to be produced, made of stucco gypsum: Thickness h = 1.2 cm = 0.012 m und width b = 1.20 m; production speed v = L/t = 60 m/min = 1 m/s, with the length L of the plates; thus: necessary volume flow rate V ̇ 1 = V/t = (h · b · L)/t = 0.0144 m3/s; for a mixer with three outlet pipes, each of them with a diameter of d = 2R = 75 mm; thus, for each single pipe counts: V ̇ = (14.4 · 10-3 m3/s) / 3 = 4.80 · 10-3 m3/s, resulting in: γ ̇ w = 116 s-1
