answer in an analytical way 13–113 Cold water (C, = 4180 J/kg · °C) enters the tubes ofa heat exchanger with 2-shell passes and 20tube passes at20°C at a rate of 3 kg/s, while hot oil (C, = 2200 J/kg · °C) en-ters the shell at 130°C at the same mass flow rate and leaves at%3D 60°C. If the overall heat transfer coefficient based on the outersurface of the tube is 300 W/m² . °C, determine (a) the rate ofheat transfer and (b) the heat transfer surface area on the outerside of the tube.Answers: (a) 462 kW, (b) 29.2 m2Hot oil130°C3 kg/sCold water20°C3 kg/s(20-tube passes)60°CFIGURE P13-113
