Hot water passes through a copper tube whose inner diameter is 20 mm thickness is 3 mm and length is 1 m. Outside cool air flows across the tube at T_inf = 290 K. The water flow rate is = .005 kg/s and the inlet and exit mean temperatures (or bulk temperatures) of the water flow are measured at T_mi = 360 K and T_mo = 330 K respectively. Use the water properties at 345 K:c_p = 4.191 KJ/(kh*K)rho = 976.6 kg/m^3 = 3.89*10^-4 (N*s)/m^2etcAssume that the water flow within the tube is fully developed.(1) Determine the average overall heat transfer coefficient U with respect to the inner surface area of the tube.(2) Is the water flow laminar or turbulent?(3) If the flow rate is doubled determine the new exit mean (bulk) temperature T_mo.
