1. The problem statement, all variables and given/known data A flexible tube can be used as a simple siphon to transfer fluid from one container to a lower container. The fluid has a density of 800. kg/m3. See the dimensions given in the figure, and take atmospheric pressure to be 101.3 kPa. There are three points given: Pt X is 10cm below the fluid line in tub from which the fluid is draining. Pt Y is 20cm above the fluid level in the tub. Pt Z is 60cm below the fluid level in the tub. What is the absolute pressure at point Y? 2. Relevant equations 1) ∆P=density x gravity x ∆height and 2) Archimedes' principle 3. The attempt at a solution I've already found the speed of the fluid in the siphon to be 3.429m/s at pts Y and Z. From the book I derived the equation 1 and tried using both .2m and .3m for the ∆h, but to no avail. I didn't forget to add the 101.3kpa to the pressure either, and since neither of the previous two answers are correct, I'm a little lost.
