Design a heat exchanger to cool down a mixture of water and ethylene glycol from 80°C to 20°C using cooling water from a nearby lake that enters at 15°C. The mixture flow rate is 10 L/min, and the desired outlet temperature is 20°C. The heat transfer coefficient for the heat exchanger is 250 W/(m².K) and the overall heat transfer coefficient is to be assumed as 350 W/(m².K). The heat capacity of the mixture is 3.8 kJ/(kg.K) and the density is 1030 kg/m³. Determine: a) the surface area of the heat exchanger required for this process,b) the volume flow rate of cooling water required, and c) the overall heat transfer rate in kW.

Here's a precise problem for a chemistry student to solve related to enzyme kinetics and inhibition:A researcher wants to determine the Km and Vmax values of an enzyme that catalyzes the conversion of substrate A to product B. They measure the initial reaction rates at varying substrate concentrations and obtain the following data:| [A] (mM) | Initial Reaction Rate (μmol/min) ||----------|---------------------------------|| 1.0 | 0.10 || 2.5 | 0.20 || 5.0 | 0.28 || 10.0 | 0.32 || 20.0 | 0.35
