  • CHAPTER 6 HEAT TRANSFER APPLICATIONS

    In a counter flow heat exchanger, water is being chilled by sodium chloride brine. If the rate of flow of the brine is 1.8 kgs-1 and that of the water is 1.05 kgs, estimate the temperature to which the water is cooled if the brine enters at –8oC and leaves at 10C, and if the water enters the exchanger at 32oC.

    The causes of brittle fracture include low temperature, high impact loading, and high sulphur content. On the night of the Titanic disaster, each of these three factors was present: The water temperature was below freezing, the Titanic was travelling at a high speed on impact with the iceberg, and the hull steel contained high levels of sulphur.
