Questiorn If the surface tension of water is 0.0728, what is the capillary rise (in meters)...
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.
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)
Capillary waves are waves that run across the surface of water because of the surface tension of the water. (You can see these waves if you gently touch your finger to the water surface in a glass of water.) If the surface tension of water is 0.07 Newtons/m, if the density of water is 1000 kg/m, and if the waves have a wavelength of 3 mm (waves this short aren't affected by gravity so ignore g), estimate the speed of...
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...
1. (10 points) A water manometer is being designed to measure the pressure on a system. What minimum tube diameter (mm) is necessary to keep the capillary height change of the water less than 2 mm? Water surface tension and specific gravity are 72.8 dyne/cm and 1.0, respectively. The contact angle for the water-air-glass interface is 15º.
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...
I need the best solution for these 2 questions on the

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.

Suppose water is raised by capillary action to a height of 5.35 cm in a glass tube. Refer to the angle values given in the table to answer the questions. Enter a positive number for height if the water is raised above the surrounding water level and a negative number if it is pushed below. What height will water reach in a paraffin tube of the same radius? paraffin tube: cm What height will water reach in a silver tube...
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...
