A shell-and-tube heat exchanger with 2-shell passes and 12- tube passes is used to heat water (cp = 4180 J/kg-K) in the tubes from 20°C to 70°C at a rate of 4.5 kg/s. Heat is supplied by hot oil (cp = 2300 J/kg-K) that enters the shell side at 170°C at a rate of 10 kg/s. For a tube-side overall heat transfer coefficient of 350 W/m2-K, determine the heat transfer surface area on the tube side.
