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.

3. Particulate matter (PM) from vehicle exhaust is entering a gym through an open window and mixing with air discharged from the air conditioning system. The air conditioning system discharges 15 m³/s of air with a low PM concentration of only 0.20 mg/m³. The PM concentration in the air entering through the window is 4.50 mg/m³. If the mixed air exiting the gym has a PM concentration of 0.75 mg/m², what is the estimated flow rate of the air entering the window of the gym?
