Water flow rate half inch PVC pipe 65 psi?
What schedule piping as schedule 40 fittings are rated for 125# thus your 140 PSI would be really dangerous to try on standard fittings
Maximum PSI rating is on the outside rating of the pipe
25 pounds per square inch = 1.72368932 bars

250 PSI WELDED
A lot
5 Pounds per Square Inch

Depends on what is flowing through the pipe and the temperature of the pipe.
As psi (pressure) increases, cfm (cubic feet per minute) generally decreases. This is because at higher pressures, air volume decreases due to compression. The relationship between psi and cfm is influenced by factors such as the compressor type, design, and operating conditions.
