A thin-walled concentric tube heat exchanger of 0.19-m length is to be used to heat deionized water from 40 to 60°C at a flow rate of 5 kg/s. The deionized water flows through the inner tube of 30-mm diameter while saturated steam at 1 atm is supplied to the annulus formed with the outer tube of 60-mm diameter. The thermo physical properties of the deionized water are P = 982.3 kg/m3, c p = 4181 J/kg ∙ K. k = 0.643 W/m ∙ K, μ = 548 x 10-6 N ∙ s/m2, and Pr = 3.56. Estimate the convection coefficients for both sides of the tube and determine the inner tube wall outlet temperature. Does condensation provide a fairly uniform inner tube wall temperature equal approximately to the saturation temperature of the steam?
