Which of the following is NOT required to calculate water pipe sizes?

To determine the appropriate size of water pipes, several factors must be considered, but maximum steel pressure is not one of them.

The maximum flow rate is essential because it helps determine the volume of water that needs to be transported through the pipes. Different flow rates will necessitate different pipe sizes to ensure that the system functions effectively without excessive pressure loss or potential overflow.

The type of pipe material also plays a critical role, as different materials have varying flow characteristics and friction losses, which affect how water moves through the pipe. The length of the pipe run is equally important because longer runs can reduce flow due to friction losses, thereby influencing the necessary diameter of the pipe.

In contrast, while maximum steel pressure may inform aspects of pipe safety and durability, it does not directly contribute to calculations regarding the size of the pipe needed for water flow. Pipe sizing is primarily concerned with flow, material characteristics, and the distance the water needs to travel.
