1. The problem statement, all variables and given/known data Water flows in the pipe below as an ideal fluid where: P1 = 1.95*10^5 Pa ; Rad @ P1 = 3cm P2 = 1.20*10^5 Pa ; Rad @ P2 = 1.50 cm P2 is above P1, but the height difference is UNKNOWN. Questions: 1. What are the velocities at P1 and P2? 2. Find volume flow rate through the pipe. I don't have a diagram, but it's pretty simple - known pressures with known radii at UNKNOWN heights. 2. Relevant equations P1 = P2 + dgh -- doesn't this assume the areas are the same? (which they aren't) Bernoulli's. A1V1 = A2V2 3. The attempt at a solution 1. I used A1V1 = A2V2 to solve the ratio between V1 and V2 (since rad can be used to find A) and solved for v1. 2. I substituted answer for v1 into v1 of bernoulli's equation. This way I can get v2. BUT, I can't solve Bernoulli's eq. without knowing the heights, h1 and h2. 3. I though P1 - P2 = dgh could work, but I thought this was only for change in height with the same area. Am I wrong? Help would be much appreciated. I'm so stuck on this whole different areas/heights/pressures thing and my brain is shutting down a bit from the frustration. Haha help?
