The discussion revolves around calculating the unknown entrance pressure in a pipe system, particularly in relation to the depth of a tank. Participants are exploring how to derive this pressure given that it is not explicitly provided in the problem statement.
The discussion is ongoing, with participants exploring different interpretations of the problem setup. There is a suggestion that the pressure at the water surface may be considered in relation to the entrance pressure, but no consensus has been reached on a specific approach.
There are uncertainties regarding the reference points for pressure measurements, particularly whether they are taken at the pipe entry and exit or at the free surface and pipe exit. Additionally, the problem includes a note that the head loss is zero, which may influence the calculations.
You are expected to find it from the depth of the tank.foo9008 said:
i am going to use this equation to solve this question , where z = 10 m what is the pressure at ENTRANCE ? it's not givenbilly_joule said:
