Selecting pumps for parallel piping that converges

So I’ve got a system with two pumps. The two 4’ lines converge into one 8’ lines after the pump discharge. I’m stuck on how to handle the TDH calculation. I don’t know whether to handle it as one system, two systems, or something in between. If anyone has any advice or can recommend somewhere to find more info I’d be very grateful
