How much water per minute will flow through a one inch PVC pipe with a pressure of seventy psi?

The flow rate through a one-inch PVC pipe at a pressure of 70 psi can be estimated using the Hazen-Williams equation, which is commonly used for water flow in pipes. Under these conditions, the flow rate is approximately 25-30 gallons per minute (GPM). However, precise flow rates can vary based on factors such as pipe length, fittings, and other system characteristics. For a more accurate calculation, specific details of the piping system would be needed.
