A heat exchange system is to be designed to cool 20 tonnes h of gasoline from 70C to 30C in a 11 shell and tube heat exchanger. The cooling fluid is to be boiling ammonia, which will be subsequently condensed on the shell side of a second 1-1 shell and tube heat exchanger that uses brine as a cooling medium. In this exchanger, the brine enters at 3C. The overall heat transfer coefficient for the gasoline cooler is 855W/(m2K) and for the ammonia cooler it is 1140W/(m2K). Design a system to achieve this objective. The heat capacity of gasoline is 2000J/(kgK)I
