How can computational chemistry be used to study protein-protein interactions and lead to the discovery of potential inhibitors for disease-related interactions? Specifically, can molecular docking studies be used to predict the binding affinity and selectivity of a small molecule inhibitor to a protein-protein interface involved in a particular disease pathway?

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.
