A flexible tube can be used as a simple siphon to transfer fluid from one container to a lower container. See the dimensions given in the figure, take atmospheric pressure to be 101.3 kPa, and use 9 = 9.80 N/kg. Neglect viscosity, and assume the tube has a fixed cross-sectional area. 20 cm 10 ch 60 cm Note that you will most likely get different numbers forthe different parts below. As usual, 3 good way to handle that is to solve the problem using variables, and only plug in numbers at the end. The fluid has a density of 880 kg/m3, and the tube has a cross- sectional area that is much smaller than the cross-sectional area of the higher container. Calculate the speed at which the fluid flows out of the tube at point Z. m/s The fluid has a density of 880 kg/m3, and the tube has a cross- sectional area that is much smaller than the cross-sectional area of the higher container. Calculate the speed at which the fluid is flowing through the tube at point Y. m/s The fluid has a density of 880 kg/m3, and the tube has a cross- sectional area that is much smaller than the cross-sectional area of the higher container. Calculate the absolute pressu re inside the tube at point Y. kPa A wooden ball with a weight of 16.0 N hangs from a string tied to a spring scale. When the ball is at rest, exactly 50% submerged in water, the spring scale reads 4.00 N. For this problem, we will use a density of water of 1000 kg/m3, and we will use g = 10.0 m/sz. Ifthe ball was only 40.0% submerged in water instead, what would the spring scale read? N A wooden ball with a weight of 16.0 N hangs from a string tied to a spring scale.

Determine the density ofthe ball. _ kg/m3 A wooden ball with a weight of 16.0 N hangs from a string tied to a spring scale. When the ball is at rest, exactly 50% submerged in water, the spring scale reads 4.00 N. For this problem, we will use a density of water of 1000 kg/m3, and we will use g = 10.0 m/sz. Determine the volume of the ball. The fluid in the U is water, and there is a 10.0 cm difference between the water levels on the two sides. Determine the magnitude ofthe pressure difference between points 1 and 2 in the Venturi tube. Pa The Venturi tube has air flowing through it. Ifthe cross-sectional area ofthe Venturi tube is 5 times larger at point 1 than it is at point 2, what is the airspeed at point 2? mls Wenturi tube is a tube with a constriction in it. Pressure n a Venturi tube can be measured by attaching a U ;haped fluid-lled device to the Venturi tube as shown in .he figure above. The density of air is 1.20 kg/m3 and the tensity of water is 1000 kg/m3. Use 3 = 10.0 m/s2. A cube ofwood,10 cm on a side, is placed in a container ofwater. The cube floats with exactly 42% of its volume submerged. The density of water is 1000 kg/m'. The density of oil is 800 kgfrn'. Now. the cube is tied to the bottom of a container that's filled with water and oil, as shown in the diagram. The string's length is such that the cube is exactly 50% in the oil and 50% in the water. Determine the tension in the string. A cube ofwood, 10 cm on a side, is placed in a container ofwater. N The cube oats with exactly 42% of its volume submerged. The density of water is 1000 kg/m3. The cube is then placed into a container ofoil. The oil has a density of 800 kg/m3. What percentage of the cube is submerged now? % water
