Here's a precise problem for a chemistry student to solve related to designing a heat exchanger for a specific process:A chemical plant produces a product with a flow rate of 500 liters per hour, and it needs to be cooled from its initial temperature of 120°C to its final temperature of 80°C before it can be packaged for shipment. The cooling medium that will be used is water, which is available at a flow rate of 400 liters per hour and an initial temperature of 20°C. Design a heat exchanger to cool the product and determine the required surface area of the heat exchanger if the overall heat transfer coefficient is 500 W/m2K.
