Heat transfer problem
Water flows through a thin-walled cylindrical tube of diameter 1 cm, maintained at a uniform temperature, ?s = 360 K. The inlet and outlet temperature of water was found to be ?i= 280 K and ?o = 355 K, respectively. (a) What is the log mean temperature difference in this case? (b) If the mass flow rate is 0.005 kg/s, what is the total rate of heat transfer from the tube to the water? (c) What is the Reynolds number corresponding to the given flow conditions? (d) Assuming fully developed flow in the entire tube, what should be the length of the tube to allow the abovementioned operating conditions ?
