I'm no good with fluid dynamics. I really am willing to improve can someone point me to what equation I should use for this question. I assume its bernoullis equation? I've drawn a diagram of how I see the pipe. To make things worse I haven't done fluids in quite a while. 1. The problem statement, all variables and given/known data 3. The attempt at a solution Please can someone give a hint on where I should start. Thank you!
