An apparatus, used in an operating room to cool blood, consists of a coiled tube that is immersed in an ice bath. Using this apparatus, blood, flowing at 0:006 m3/h; is to be cooled from 40 to 30°C. The inside diameter of the tube is 2.5 mm, and the surface coefficient between the ice bath and outer tube surface is 500 W/m2 K: The thermal resistance of the tube wall may be neglected. Determine the required length of tubing to accomplish the desired cooling. Properties of blood are the following:

Determine the total heat transfer to the oil and its temperature at the heater exit.
