Distribution of water through a pipe network

I have a network of stainless steel pipes that are distributing water throughout a building.

I know the flow rate of water entering the system is 600 IGPM, but am unsure of how this water will be distributed. I have attached a simplified schematic of what the pipe network looks like.

Is it safe to assume the flow rate throughout this network will be the same, even though the diameters change, based on the continuity equation?

A1*V1 = A2*V2

• No, changing diameters will have an effect, as will the different lengths and how many bends there are as they all add losses in terms of pressure drop or head. – Solar Mike Jan 29 '20 at 18:56
