A complete-mix flow reactor is designed to treat an influent waste stream containing 130mg/L of casein at a flow rate of 80 liters per minute (lpm). Assume that casein removal follows first-order removal kinetics with a rate constant, k, of 0.5h-1 and that the effluent should contain 13 mg/L of casein at steady state. Determine: a. the detention time in hours b. the volume of the reactor in cubic meters

Mechanical Processes

In civil engineering, the materials have to undergo a series of manufacturing processes before using them in construction and structural applications. These manufacturing processes form the foundation stone of mechanical processes. Some of the civil engineering materials such as bars, metallic beams, metallic columns, surveying equipment, earthmovers, overhead cranes, structural and construction components, and even cement that is the most fundamental construction component need to undergo different manufacturing processes before they are ready to use. These processes are mechanical.
