1. The problem statement, all variables and given/known data

Let's say the surface of the fluid is very big as compare to the tube diameter.
Are my assumptions below correct?


VB(inlet of the tube) = VE, i think so because the diameter of the tube is constant.
And the velocity through the tube all are constant.

or VB(inlet of the tube) = 0? but it could be right?

Which point has the lowest pressure? should be PC or PE?

Are the pressure of PB and PE the same?

Is the PD = 0?

will all the pressure be different value if the fluid in a stationary motion?

thanks all.
