Hello All,

I have an interesting and may be a simple question on fluid flow.

Let us assume, case 1 we have cylindrical pipe where the flow enters at inlet pressure P1 and exits at outlet pressure P2 for given length (P1>P2). In case 2, we have same cylindrical pipe with some blockage in middle of the pipe. The only difference is blockage within the pipe.

Now, the question is pressure P1 in both case 1 & case 2 will it still remain the same if the pressure P2 is same in both cases. If Yes/No, kindly explain the physics scenario.

Might be my question look silly. But I'm looking for proper explanation.
