- Trying to calculate the pressure of water exiting a 1/32" hole in a closed 1" pvc pipe

I have a 1" PVC pipe that is 36" long, closed on one end and hooked up to a pump on the other. The pipe has 10 holes each measuring 1/32" in diameter and I have been trying to use Bernoullis equation to find the pressure of the water exiting those holes. I believe the volume of water that will exit the holes will be 0.16g/min/hole so I wanted to use a pump that has a flow rate of 5 gallons/ min at 60 psi. If I am wrong and the volume exceeds what is pump can provide I can change the pump to one with a higher flow so assuming that no matter what, the pressure at the start of the pvc is 60psi and the flow will 5 g/m or equivalent to the volume of water lost, what is the pressure of the water exiting the holes. I am trying to make a powered sprayer for cleaning a pool filter and was hoping to estimate the pressure so I can choose an appropriate pump and also ensure I do not blow a hole through the cartridge but I am stuck on plugging my numbers into the equation. Any help is appreciated.
