The surface of a furnace wall is at a temperature of 1350oC. The outside wall temperature is 42oC. The furnace wall is made of 25 cm of refractory material having a thermal conductivity of 1.4 W/moK. The outside wall is steel, 1 cm thick with thermal conductivity of 47 W/moK. Calculate the thickness in meters of brick to be installed in between the refractory material and steel if its thermal conductivity is 0.28 W/moK and the heat loss is not to exceed 750 W/m2.
. A counterflow heat exchanger is designed to cool 0.65 kg/sec of oil with specific heat Cp = 3.4 KJ/kgoK from 150oC to 70oC. Water for cooling, Cp = 4.18 KJ/kgoK is available at 20oC and flow rate of 0.6 kg/sec. Calculate the length of a 3.5 cm inside diameter tubing in meters. The overall coefficient of heat transfer is 90 W/m2 oK.
