Main Question or Discussion Point

Hello Everyone,

Can someone please explain to me how I would go about verifying the External Static Pressure of a pump that feeds a pressurized fire fighting network with loops in it. An image of the network is attached. I'm not being able to grasp the concept of pressure drop in a pressurized loop and to imagine the hydraulics involved.

Thank you for your response

The key is flow. If there is no flow, the only variation in pressure will be the result of elevation changes.
If there is flow, then you basically have a resistor network. So the changes in pressure will be elevation plus the affects from flow.
