10 00 R %24 Homework 6 3.Water is flowing in a pipe that has varying cross-sectional area throughout, and at all points the pipe is completely filled with water. At one point the cross-sectional area of the pipe is 0.07 m^^2, and the velocity of the fluid is 3.50 m/s. What is the fluid velocity in the pipe where the cross sectional area is instead (a) 0.105 m^2 and (b) 0.067 m^2. (c) also calculate the volume discharged from the end of the pipe in one hour (Hint: Use volume flow rate eq. V/t=A*v and solve for V) Q=AV 0.105*0.067= f12 f8 114 A f4 十百 & 7. 4.

Three glass containers containing water of the same temperature have different shapes and thickness. The distance between the top surface of the water and the bottom of each glass container is the same. Which of the following statements correctly characterizes the pressure at the bottom of the glass containers? (explain why) 2 3 a. Pressure at the bottom of all glass containers is the same. b. Pressure at the bottom of (2) and (3) are the highest because they have the same volume. c. Pressure at the bottom of (2) is the highest because it is wide. d. Pressure at the bottom of (1) is the highest because it is narrow. e. Pressure at the bottom of (3) is the highest because it is vertically aligned.

The spring of the pressure gauge shown in the figure below has a force constant of 1 350 N/m, and the piston has a diameter of 1.40 cm. As the gauge is lowered into water in a lake, what change in depth causes the piston to move in by 0.700 cm? 4.635 X Your response differs from the correct answer by more than 10%. Double check your calculations. m Vacuum
