Design a counter-current heat exchanger to cool 10,000 liters per hour of cyclohexane at 110°C down to 50°C, while heating 7,500 liters per hour of water at 25°C up to 80°C. The cyclohexane will be cooled by water which enters the heat exchanger at 90°C and exits at 60°C. The overall heat transfer coefficient is expected to be 1,000 W/m2K. Determine the required heat transfer area and the pressure drop across the heat exchanger.
