How many gpm of water flow through a 2 inch pipe at 100 psi?

The flow rate of water through a 2-inch pipe at 100 psi can be estimated using hydraulic calculations. Generally, a 2-inch pipe can flow around 40-50 gallons per minute (GPM) at that pressure, depending on factors like pipe length, fittings, and friction loss. For precise calculations, it's best to use the Hazen-Williams equation or consult flow tables specific to the pipe material and conditions.
