A tube can be inserted into the top of a pipe transporting liquids, providing the pressure is relatively low, so that the liquid fills the tube at height h. Determine the pressure in a water pipe if the water seeks a level at height h=4ft above the center of the pipe. I'm asking you guys if there is a definite answer to this problem. There seems to be insufficient information such as the diameter of the pipe. Plus, is the pipe horizontal or vertical? I'm guessing horizontal due to it "transporting liquids". Would the answer just be a simplified version of the formula incorporating the 4ft? If not, what am I missing?
