Hi,

I have a compressible fluid passing through an inlet to two outlets 1 and 2 in Manifold. I was trying to find fluid flow distributions at two outlets and as well as Pressure drop.

However, I am not sure how to interpret Pressure drop values from Total Pressure Results of Inlet and Outlets?

For example: Total Pressure value at Inlet - 48.3 Pa
Outlet 1 - 39.5 Pa
Outlet 2 - 36.3 Pa

Should I subtract Pressure values of Outlet 1 and 2 from Inlet?

Will that give me Pressure drop?

Or should I just subtract Outlet 1 from Outlet 2?


Your response will be highly appreciated! Thanks

Here is the results of Fluid distribution and Total Pressure.

Trying to understand how to read Pressure drop values from this.

Yes, of course. That is the pressure necessary for driving the flow.

Thank you for your respond. I tried it that way. But the value shows me in negative.

Meaning - Inlet 48 Pascal and Outlets 39.5+36.3 Pascals = 75.8

So, total pressure drop = 48 - 75.8 = -27.8 Pascal

This is where I am confused. Pressure drop value is in negative? Does it make sense?

Thanks!

Not this way.

You have a pressure difference of 48-39.5 = 9.5 Pa for driving the flow from inlet to outlet2 and another pressure difference of 48-36.3=11.7 Pa for outlet2.

Makes sense now. Thank you so much for your help!
