A one-shell pass and two-tube passes heat exchanger must transfer 300 kW to a solution with a specific heat of 3.28 kJ/kg-K and change its temperature from 60 C to 88 C. Steam is available at 120 C. The unit convective coefficient is 3 200 W/m2-K for the inside and 8 500 W/m2-K for the outside. The thermal conductivity for the tubes is 115 W/m-K and the tubes have 4 cm OD and 3 cm ID and are 3
