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...

0.30 m LEARN MORE QUESTION Based on the result of this calculation, is capillary action likely to be the sole mechanism of water and nutrient transport in plants? Explain. (Select all that apply.) No, unrealistically narrower tubes would be needed for taller plants. No, the capillary tube in the example is already unrealistically wide and wider tubes would be needed for taller plants. No, many plants are much taller than 0.3 m. Yes, because evaporation of water from the leaves...

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...

Questiorn If the surface tension of water is 0.0728, what is the capillary rise (in meters) in a glass tube that is 1.0 mm in radius? Your answer should have two significant figures. Use Pwater 1.0for the density of water. 0 for the density of water cm Use98for the acceleration due to gravity. Assume the contact angle, θ is equal to 0 . . Provide your answer below:

A bromobenzene 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 bromobenzene less than 2 mm? Bromobenzene surface tension and specific gravity are 42.5 dyne/cm and 1.75, respectively. The contact angle for the bromobenzene-air-glass interface is 35°.
