3. 0.5 kg/s of ethylene glycol flow through a thin-walled copper tube of diameter 1.25 cm; 0.375 kg/s of water flow in the opposite direction through an annulus surrounding the tube. The ethylene glycol, which enters at 100C, is required to leave at 60C, while the water enters at 10C. Calculate the exit temperature of the water and the length of the tube required. Cp for water = 4.18 kJ/kgK; Cp for ethylene glycol = 2.65 kJ/kgK; U = 2.90 kW/mK.
