Question

3. Determine the gage pressure at the center of pipe A in both psi and kPa. ANSWER: PA-5.72 psig 4. The ratio of the container diameter to the tube diameter is 10. When air in the container is at atmospheric pressure, the free surface in the tube is at position 1. When the container is pressurized, the liquid in the tube moves 3.0 ft up the tube from position 1 to position 2. What is the container pressure that causes this deflection? The specific weight of the liquid is 50 Ibt/t ANSWER: PCentain IL- Tube lo Liquid Centainer 82-
