Final answer:
In a piping system, the size and installation must meet the flow rate demand.
Step-by-step explanation:
The piping system must be sized and installed to meet the flow rate demand. The flow rate is the volume of fluid that passes through a particular point in the piping system per unit of time. To ensure continuity of flow, the amount of fluid that flows past any point is constant, regardless of the size of the opening or the flow rate. The flow rate can be calculated using the formula:
Flow rate = Area x Velocity
Therefore, the piping system must be sized and installed to accommodate the desired flow rate, which in this case is determined by the required speed of the water at the small end of the tapered pipe.
