Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

b) What is the copper concentration in mg/L immediately
downstream of the copper plating facility?
c) How many kg per day are contributed to the receiving
stream by the copper plating facility?
