2. A mixer with a four-blade inclined turbine that obeys the standard design proportions. It has a blade width ( W) of 55 mm. The tank is filled with a 65%KOH aqueous solution with a density of 1.52Kg/L and a viscosity of 15cp. The turbine rotates at 1250 rpm. What power will it require?
Da=2.46ft=0.749 m N=120rpm N=60120=2 rps ρ=78lb/Ht3=1249.4 kg/m3 μ=30CP=30×10−3 Pa⋅S ⇒NRC′ NRe′=μDa2NS=(30×163)(0.749)2(2)(1249.44) NRl′=4.6×104 (from the graph curve 1 is for flat blede disk turbine, at N′=4.6×10∘ ? disk turbinc, at NRe ′=4.6×10∘} we get, Np=5 have, NP=ρN3D95P P=Np×9×N3×D45=5×1249.44×(2)3×(0.749)5
3. A system similar to the previous one but with a flat turbine (W=75 mm) mixes a polymeric compound (PEG) with a viscosity of 260 Pas and a density of 960Kg/m3. What will be
