I'm getting ready to plumb my 90

Can someone explain to me why I keep seeing diagrams of tank drains having 90-degree angles attached to the bottom of the bulkheads then being run with plumbing or reinforced clear hose back to the sump's inlet bulkhead with yet another 90-degree angle? Why not run directly from one bulkhead to the other? I didn't know if there was a specific reason for the angles or not?

on 3/4" PVC thats like 4.5' of straight pipe each 90 in friction loss

So, you're saying it's to slow the flow of the drain? For noise factor?

I'm betting there is no good answer other than they think it looks better.
