What is the resulting pressure suitable for a wheel line sprinkler system when the elevation difference is 45 feet?

To determine whether the pressure is suitable for a wheel line sprinkler system given an elevation difference of 45 feet, it's important to understand how elevation affects water pressure. Water pressure decreases by approximately 0.433 psi for every foot of elevation gain. Therefore, for a 45-foot elevation difference, the pressure loss would be calculated as follows:

45 feet * 0.433 psi/foot = approximately 19.485 psi.

This means that if the original pressure was close to or below this value, it might not be sufficient to ensure proper sprinkler operation. For a wheel line sprinkler system to function effectively, it typically requires a minimum pressure range depending on the specific design and size of the system. If the resulting pressure after accounting for the elevation loss does not meet this minimum requirement, then it would indeed be insufficient, confirming that the psi is not high enough for optimal performance in this scenario.

Knowing this, recognizing that the pressure after the elevation change would be inadequate aligns with the reason for selecting this option.
