1. The problem statement, all variables and given/known data I am looking at the following system: It shows a pore/tube (B) which is attached to a reservoir A. The fluid in reservoir A has a non-zero velocity in the horizontal direction, but I assume that the tube B is so long that the velocity there is unaffected and still zero. Based on Bernoulli's law, can I conclude that the pressure in reservoir A is lower than that in tube B due to the velocity difference? Note that i neglect the effects of gravity etc., I assume the system is in a plane.
