Select one: mass and density depth and density weight and volume depth and volumeThe pressure in a fluid at rest decreases with depth. Select one: True False
- QUESTION 4 The tank, shown in figure 2, contains oil and water. The width of the tank is 4 m. The density of the oil is 850 kg/m³. Calculate the resultant force acting on the side wall of the tank and the position where it acts on the side wall. 6 m Oil Water 4m Figure 2HYDROSTATIC FORCE ON CURVED SURFACE2. A circular ring (radius = 5.0 cm) is used to determine the surface tension of a liquid. The plane of the ring is positioned so that it is parallel to the surface of the liquid. The ring is immersed in the liquid and then pulled upward, so a film is formed between the ring and the liquid. In addition to the ring's weight, an upward force of 3.6 x 10 N is required to lift the ring to the point where it just breaks free of the surface. What is the surface tension of the liquid?
- HYDROSTATIC FORCE ON PLANE SURFACEWhat is the specific volume of air at 15 Psia and 90F degrees in ft3/lb?
