D. D. Steam Liquid water 1 kg/s of water at 20°C enters an annular section formed by an outer tube of diameter De = 100 mm and an inner tube of external diameter D, = 25 mm [internal diameter D; = 21 mm; thermal conductivity of 40 W/(K m)]. The length of the double tube is ## m. Saturated steam flows through the inner tube at 100°C with a convection coefficient of 5000 W/(m² K). The external surface of the heat exchanger is well insulated, avoiding losses to the environment. At what temperature does the water come out? Prandtl number Pr = Reynolds number Rep = Friction coefficient c = Nusselt number Nup = Convection coefficient h, = W/(m? K) Global coefficient U,= W/(m² K) Outlet temperature TE= K.

the tube length is 1m.

Steam D.De Liquid water 1 kg/s of water at 20°C enters an annular section formed by an outer tube of diameter De = 100 mm and an inner tube of external diameter D. = 25 mm [internal diameter D; = 21 mm; thermal conductivity of 40 W/(K m)]. The length of the double tube is ## m. Saturated steam flows through the inner tube at 100°C with a convection coefficient of 5000 W/(m2 K). The external surface of the heat exchanger is well insulated, avoiding losses to the environment. At what temperature does the water come out? Prandtl number Pr = Reynolds number Rep = Friction coefficient cf = Nusselt number Nup = Convection coefficient h, = W/(m² K) Global coefficient U, = W/(m² K) Outlet temperature TE = K

Follow-up Question

Thank you for this answer. I don't quite understand step 4, 5 and 6 because the operation is not really readable : could you write it with parenthesis and clear opeartion signs (+, x, /, ^) ?
