8.6 In an open heart surgery under hypothermic conditions, the patient's blood is cooled before the surgery and rewarmed afterwards. It is proposed that a concentric tube counterflow heat exchanger of length 0.5 m is to be used for this purpose, with a thin-walled inner tube having a diameter of 55 mm. If water at 60°C and 0.1 kg/s is used to heat blood entering the exchanger at 18°C and 0.05 kg/s, what is the temperature of the blood leaving the exchanger and the heat flow rate. Take Up = 500 W/m2 K, of blood = 3.5 kJ/kg K and of water = 4.183 kJ/kg K. =
