Hi all,

I need help to solve a problem:

In a water pump system, consider pump as a bilateral nozzle (both horizontal). So, due expansion case, when pipe expands and due friction force by support, a reaction force transmits efforts against discharge nozzle which is higher than allowable by pump.

I think the better way to reduce this force is eliminating friction force is replacing support for a rod. Am I right?

Data:

Discharge Nozzle Diameter: 20"
Pipe diameter after: 32"
Pressure: 5.8 bar
Temperature variation: 5° C

Also, I can't use expansion joint, because F = P*A will be higher than force due friction.

Somebody can help me?

Thanks in advance,

Miyamoto
