how do you convert psi water pressure to gallons per minute?

you cannot directly convert psi to gpm. they are two different units of measure. psi measures pressure, and gpm measures flow rate. however, if other variables are known, you can use bernoulli's equation to indirectly make a conversion. the following assumes the flow is in a pipe and the pipe diameter is known. it also assumes a steady state incompressible flow.read more≫
