1. A pressure gauge located at the base of an open tank containing a liquid with a specific weight of 13.6 kN/m3 registers 1.27 MPa. What is the depth of the fluid in the tank? 2. A 13-in diameter displacer is used to measure changes in water level. If the water level changes by 1.2m, what is the change in force sensed by the force sensor? 3. A 7.3-in diameter displacer is used to measure acetone levels. What is the change in force sensed if the liquid level changes by 2.3 ft? 4. A 1.3m-long capacitive probe has a capacitance of 31 pF in air. When partially immersed in water with a dielectric constant of 80, the capacitance is 0.97 nF. What is the length of the probe immersed in water? 5. How far below the surface of the water is the end of a bubbler tube, if bubbles start to emerge from the end of the tube when the air pressure in the bubbler is 263 kPa? 6. What is the depth of the liquid in a container if the specific weight of the liquid is 56 lb/ft3, the container weighs 33 lb, and has a diameter of 63 in? A load cell measures the total weight to be 746 lb.
