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.

Design a continuous stirred tank reactor (CSTR) for the exothermic reaction A + 2B -> C with the following conditions: - The reactor should produce a minimum of 5 moles of product C per hour- The feed ratio of A to B should be 1:2- The temperature of the reactor should not exceed 50°C- The volumetric flow rate of reactant feed is 10 L/hour- The reactor should have a residence time of at least 4 hours. Assuming all reactants are available in excess, determine:- The required volume of the CSTR- The heat generated by the reaction- The cooling rate required to maintain the reactor temperature below 50°C

Assuming you have a mixture of ethanol and water, design a distillation column that can achieve a 95% purity of ethanol in the distillate using the minimum number of plates possible. The feed to the column contains 40% ethanol and 60% water, and the distillate and bottoms products need to be at least 95% pure. The column operates at atmospheric pressure and the feed rate is 100 kg/hr. Also, determine the reflux ratio required to achieve this separation.
