Product description
9.12. Calculate the mass of sediment obtained on a cylindrical electrode by electrophoresis of an aqueous clay suspension. The length of the electrode l = 1 · 10–2 m; the radius of the inner electrode r2 = 0.5 · 10–3 m,
outer radius r1 = 14 · 10–3 m; voltage at the electrodes U = 5V; e is 81; n = 1 · 10-3 Pa * s; e '= 30 · 10-3 V; t = 10 s; c0 = 0.5 · 10 ^ 3 kg / m3; cm = 1 · 10 ^ 3 kg / m3.
