Consider a shell and tube heat exchanger with single tube passes with the following specs: Note that: v== a. Hot side (Shell) carries a chemical with the following data: Ph= 854 kg/m', Thi = 400 K, m =10.248kg / s, Pr=5.46, Pr,= 5.32, F0.00156 N.s/m? Cp = 1.118 kJ/kg-K, k 0.338 W/m-K, b. Cold side (Tubes) carries water with the following data: pe = 1000 kg/m', Pr = 7.56, Ti = 290 K, c, = 4.184 kJ/kg-K, F1.08x103 N.s/m2 k = 0.598 W/m-K, m. = 6.0kg /s The Aluminum circular tubes (k = 237 W/m-K) have inner and outer diameters of (D; = 2.4 cm, D. = 2.5 cm). The cross section of the heat exchanger is shown in the following Figure. ST = St = 8 cm., NT= NL = 10, N= 10*= f00 Side View Cross Sectional View Sy/2 Baffles S/2 | O o o O O O 15 cm The baffles create a geometry that resembles a flow over bank of tubes. Find the length of the heat exchanger and exit temperature for the hot and cold fluids? Hint: guess L=50 cm and check at the end
