A shell-and-tube heat exchanger with 2-shell passes and 12-tube passes is used to heat water (Cp = 4180 J/kg · °C) in the tubes from 20°C to 70°C at a rate of 5 kg/s. Heat is supplied by hot oil (Cp = 2300 J/kg · °C) that enters the shell side at 170°C at a rate of 15 kg/s. For a tube-side overall heat transfer coefficient of 600 W/m2 · °
