You can't really say. The flow rate (perhaps measured in gallons per minute) depends on the details of the entire Plumbing system between where the pressure is applied and the exit. When I say details it means thing like the total length of pipe, the internal roughness of the pipe (which changes over time) and even how many bends and how they are laid out in the pipe.
A pressure rating refers to the qualified operating pressure that is recommended for a component or a system by the manufacturer. The pressure rating of 12 schedule 40 steel pipe is 370 psi.
Fill up a 5 gal bucket of water at full pressure and time it.
This depends on what your target pressure is. If the height of the pipe is H in feet, the pressure at the bottom of the pipe from the column of water is 0.036127292 * H * 12 where 0.036127292 is the density of water in lbs/in^3. Thus, if your initial water pressure is I, the pressure at H feet will be I - 0.036127292 * H * 12 So you will have Height | Pressure +--------- 0 ft | 40 psi 10 ft | 35 psi 20 ft | 31 psi 30 ft | 27 psi 40 ft | 23 psi 50 ft | 18 psi 60 ft | 14 psi 70 ft | 10 psi 80 ft | 5 psi 90 ft | 1 psi 100 ft | 0 psi One will be required above 90 ft. You'll probably want one above 40 ft. Derivations: eq means equals. This wiki eats equals signs. D eq diameter of the pipe in inches, H eqheight in feet D / 2 eq R Area (A)(in^2) eq pi * R ^ 2 Volume (V)(in^3) eq A * H * 12 eq pi * R ^ 2 * H * 12 Water weight (W)(lbs) eq V * 0.036127292 eq pi * R ^ 2 * H * 12 * 0.036127292 Pressure (P)(psi) eq W / A eq V * 0.036127292 eq pi * R ^ 2 * H * 12 * 0.036127292 / pi * R ^ 2 eq H * 12 * 0.036127292

You can dig to the pipe, clean it and roughen it, then use purple primer and Weld On 711 to repair it. . I would wait 12 hours for this to cure then do another coat of 711. - I have done this on PVC pipe that was carrying mains water at 85 psi.
13 psi front, 12 back
The volume of a 12 inch x 12 inch pipe is: 1,360 cubic inches

Nanometers (nm) and pounds per square inch (psi) are units that measure different things, so direct conversion between them is not possible. Nanometers measure length while psi measures pressure. To convert between the two, you would need additional information like the area over which the pressure is being applied.
