How much water is discharged from 10 sprinkler heads operating at 30 psi over 30 minutes?

To determine the amount of water discharged from 10 sprinkler heads at a pressure of 30 psi over a duration of 30 minutes, it is essential to understand the flow rate of water through each sprinkler head.

In general, the flow rate of a standard sprinkler head operating at 30 psi is roughly 0.5 gallons per minute (gpm) per head. Therefore, if one sprinkler head discharges 0.5 gpm, ten sprinkler heads would collectively discharge:

0.5 gpm per head multiplied by 10 heads equals 5 gpm.

Now, to find the total discharge over 30 minutes, we can multiply the combined flow rate of the heads by the total time in minutes:

5 gpm multiplied by 30 minutes equals 150 gallons.

However, the choices provided indicate much larger volumes, implying they may be considering a more substantial flow rate typical of larger systems or different design parameters.

Considering the size of the provided answers and assuming the typical use of sprinkler systems and their operational parameters, if the flow rate per head or some additional factors such as operation of larger or higher-capacity heads are considered, the total amount of water could reach much higher figures.

In this context, when calculated under operational assumptions typically
