Design a heat exchanger for a factory that produces 10,000 liters of sulfuric acid per day starting at 70°C and needs to be cooled to 40°C for packaging. The available cooling water supply from the local municipal is at 20°C and is available at a flow rate of 1000 liters per minute. Design the heat exchanger to achieve the required temperature drop and calculate the heat transfer coefficient and the overall heat transfer coefficient.
