What is the total pressure loss for a pipe run of 200 feet losing 2 psi per 100 feet?

To determine the total pressure loss over a 200-foot pipe run, knowing that the pressure loss is 2 psi for every 100 feet is essential. This type of calculation is based on the principle that pressure loss is directly proportional to the length of the pipe.

In this scenario, if the pipe loses 2 psi over the first 100 feet, then for an extended length of 200 feet, the pressure loss will simply be doubled. By multiplying the pressure loss for 100 feet by 2 (for the additional 100 feet), the calculation proceeds as follows:

2 psi (per 100 feet) x 2 = 4 psi.

Thus, the total pressure loss across the 200-foot pipe run is accurately calculated to be 4 psi, confirming that this is indeed the correct answer. This approach underscores the importance of consistency in calculations related to fluid dynamics and pressure loss in irrigation systems.
