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...

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...

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...
