In a 1 m long double-pipe heat exchanger made of stainless steel, a temperature of 80 °C flowing through the center pipe at a speed of 40 kg/s hot water to 45 oC; It is cooled by the cooling water at 25 oC flowing between the two pipes at a speed of 30 kg/s. Coefficient of thermal conductivity 16 The inner diameter and outer diameter of the inner tube of the heat exchanger with W/ m.oC are 0.014 m and 0.015 m, respectively3; inner and outer diameter of outer tube respectively 0.022 m and 0.0225 m. Convective heat transfer coefficients according to indoor and outdoor area are 531457 and 513015 W/m2, respectively. °C. specific of water heat capacity can be taken as 4.18 kJ/kg. C on average. Using this data; a) Cold water outlet temperature (oC) b) Transferred heat(kW) c) Calculate the total heat transfer coefficient according to the interior area.
