Water (cp=4.182 kJ/kg.K, k=0.6405 W/m.K, Pr=3.57, ν=0.5537x10-6 m2/s, ρ=998 kg/m3) flows through a tube (D=0.5 cm) with an average velocity of 0.2 m/s. The average temperatures of the water at the inlet and outlet cross-sections are 16,21 oC and 78,49 oC, respectively. The uniform heat flux of 0,58 W/cm2 is subjected to the surface of the tube for heating process. Determine the tube length [m].
