## How do you convert GPM to PSI?

Similarly, how do you calculate psi from flow rate? to get this, divide the total pressure drop by the pipe length and multiply by 100. in this case, it is 10 divided by 200 times 100, which equals 5 psi. to get the flow, multiply 3.0877 by 5 raised to the power of . 5415, which equals 7.38. the flow is 7.38 gpm.
