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.

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.

Water is poured into a u-shaped tube that’s open on both ends. Oil (typical) is poured into one end until it reaches a height of 25 cm above the surface of the water. How much does the water rise on the other end of the tube from it’s original level?

Suppose you have a perfectly wetting glass tube (with air as the non-wetting phase), and the contact angle is 0˚. Assume room temperature. (There is a table of surface tension for various temperatures in the slides.) In all these calculations, please be aware of the difference between degrees and radians, and ensure that your calculator or excel functions are set up properly. 1a. How high up a 0.12 mm diameter glass tube will capillary pressure be able to pull water...

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...
