Water resources. PROBLEM 1: Capillary Tube Hemispherical Gate Above is a tank full of pure water with a depth, D = 3 m (and water below the level of the gate). A hemispherical gate is present as well as a glass tube as shown with the following details: • Hemispherical gate has diameter of 500 mm. • Capillary tube has diameter of 5 mm. Part a.) Find the total force on the gate. Part b.) Draw the force vector that...
The figure shows the effect of tube radius on the height to which capillary action can raise a fluid. In this problem, assume the contact angle for water and glass is 0 degrees. The surface tension of water is .0728N/m Calculate the height, in meters, for water in a glass tube with a diameter of 1.7cm, a rather wide tube like the one on the left. What is the radius, in meters, of the glass tube on the right if...
9.0 kg of mercury are poured into a glass u-tube. The tube's inner diameter is 1.2 cm and the mercury oscillates freely up and down about its position of equilibrium (x=0). Calculate the spring constant for the oscillation and the period of oscillation. You may safely ignore any friction of surface tension effects. r= 13.6 x 10 /?
4. 5 points A device for sampling water in lakes and streams consists of a 2.25 cm diameter cylindrical tube that is 3 cm in length. The disks are placed in a wand that allows the technician to insert the sampling disk into the water. The tubes are then sealed in a container and taken back to the lab where the water is removed from the tube and analyzed. The tube is made of glass and contains 200 cylindrical pores...
A glass tube of inside diameter 1.0 mm is dipped vertically into a container of mercury, with its lower end 1 cm below the mercury surface. a) What must be the gauge pressure of the air in the tube to blow a hemispherical bubble at its lower end? (Answer: 1400 Pa) b) To what height will mercury rise in the tube if the air pressure in the tube is 3000 Pa below atmospheric? The contact angle is 140 degrees and...
A mercury thermometer consists of a glass bulb completely full of mercury. This is connected to an empty vertical glass tube of radius 0.01 cm. If the volume expansivity of mercury is 1.81 10−4 K−1, and the top of the mercury rises 2.3 cm for a 10◦C change in temperature, calculate the volume of the glass bulb. [Assume the expansivity of the glass is negligible when compared with that of the mercury.] Answer: 0.399 cm^3
Question 1 Find the wall tension (in N/m) in the aorta and a capillary under the following assumptions. (a) The average blood pressure in the aorta is 100. mmHg, and the diameter of the aorta is 1.51 cm. ---------- N/m (b) The average blood pressure in the capillary is 25.0 mmHg, and the diameter of the capillary is 8.14 µm. ----------- N/m Questoin 2 Water is transported upward in a plant through xylem tissue, which consists of cells of 1...
Water at 15 degrees Celcius (surface tension is 0.0742 N/m) stands in a clean glass tube of 1.5-mm diameter at a height of 45 mm. What is the true static height?
