A double-pipe heat exchanger is to be used to heat 6000 kg/h of 22 mol per centhydrochloric acid. The exchanger will be constructed from karbate (imperviouscarbon) and steel tubing. The acid will flow through the inner, karbate, tubeand saturated steam at 100ŽC will be used for heating. The tube dimensionswill be: karbate tube inside diameter 50 mm, outside diameter 60 mm; steel tubeinside diameter 100 mm. The exchanger will be constructed in sections, with aneffective length of 3 m each.How many sections will be needed to heat the acid from 15 to 65ŽC?Physical properties of 22 % HCl at 40ŽC: specific heat 4.93 kJkg1ŽC1, thermalconductivity 0.39 Wm1ŽC1, density 866 kg/m3.Viscosity: temperature 20 30 40 50 60 70ŽCmN m2s 0.68 0.55 0.44 0.36 0.33 0.30Karbate thermal conductivity 480 Wm1ŽC1.
