What is flow of water through a half inch copper pipe at 35 psi?

The flow of water through a half-inch copper pipe at 35 psi can be estimated using the Hazen-Williams equation or similar hydraulic formulas. Generally, a half-inch pipe can deliver approximately 5 to 10 gallons per minute (GPM) at that pressure, depending on factors like pipe length, fittings, and flow conditions. For a more precise calculation, additional parameters such as the specific setup and any friction losses would need to be considered.
