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?
N Determine the capillary rise of water in glass tube if the surface tension of water=0.00287 N/m and diameter =80 mm (Non-anonymous question ) (3 Points)
7. Two capillary tubes are placed vertically in an open container of water. One tube has a diameter of 2.0 mm, and the other a diameter of 1.0 inch. In which tube will the water rise higher? 8. A sliding plate viscometer, as shown below, is used to measure the viscosity of a fluid. The plate area is 0.75 fr. A force of 1.5 x 10 lb moves the upper plate at a velocity of 10.0 ft/s. What is the...
please show all your work! thanks A capillary tube with a radius of mm is inserted vertically into a container of water. As shown in the picture at right, water wets the inner wall of the capillary with a contact angle of 0°. The surface tension force, Fst, (or capillary force in this context) draws water up the tube until the meniscus reaches a level of hw above the water level in the container. You may assume that surface tension...
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...
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...
What is the capillary rise of ethanol in a glass tube with a 0.1 mm radius if the surface tension of ethanol is 0.032Jm2 and the density of ethanol is 0.71gcm3? Assume that the contact angle of ethanol in a glass tube is 0 degrees. Your answer should have two significant figures.
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 wan 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 1 mm in diameter that run...
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...
10. The bottom of a glass pan containing 6.3 kg of water is 1.4 cm thick and is resting on a hot stove. The area of the bottom of the pan is 1250 cm2. At the instant the water inside the pan is at 27°C, the rate of change of he temperature of the water is measured at 2.0 C° per minute. At this instant, what must be the temperature of the surface of the pan that is in contact...
