you need to square it

area of 2x600 mm is less than half of 1x1350 mm

you can increase the flow rate by upping the pressure, but got limit also or the pipe will pecah again

Pressure need to increase with the faster flow rate, they cannot just keep on increasing pumping pressure and flow rate. Most likely will need to reduce a bit of pumping pressure if they do not want the new smaller pipes to burst too.

just a random figure i googled



edit:
from the picture, take for example 40 psi,
big pipe ~230 gpm
2xsmall pipe ~2 x 50 gpm

if you want to maintain the flow rate at 2 x 100 gpm, the pressure in the smaller pipes would go > 100 psi.

so yeah, most likely they will need to reduce the pressure a bit.

in practice, the frictional losses would also reduce some of it.
