I am mostly mechanical and have almost no experience with fluid mechanics. I experimented with 3/4 diameter garden hose, connected to the city water supply, on the end of which was a cap with a drilled 2mm hole. I currently have no practical method to check the pressure of the supply but it...
I need to build a device to test the water resistance of a piece of restaurant equipment. The device must deliver 2.5 GPM of water through a nozzel with an opening of 2mm. Can someone please give me a formula to calculate the required PSI to deliver the needed volume of water?
Thank you.
