A steel pipe is connected to a copper pipe in a galvanic corrosion couple where the electrolyte is seawater. The corrosion current density of the steel pipe is 3.2 mA/cm2. If the surface area of the steel pipe is 5 cm2, calculate the total amount of charge transferred per hour. Also, calculate the weight loss of the steel pipe per year due to galvanic corrosion, assuming the density of steel is 7.85 g/cm3.

A chemical engineering firm has been tasked with designing a chemical reactor for the synthesis of ammonia gas from nitrogen and hydrogen gases. The plant requires a production of at least 1000 kg/h of ammonia gas, and the reactor should operate at a pressure of 200 atm and a temperature of 400°C. The student should determine the optimal size and design of the reactor by considering the reaction kinetics, thermodynamics, and fluid dynamics principles. The student should also select appropriate catalysts and determine the flow rate of the reactants required to achieve the desired production rate.
