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...

3. A papercip made of steel wire (psteel-7500 KE/m3) floats in water supported by surface tension (o-0.073 N/m). This paperclip has length =50 mm, cross-section diameter 1.5 mm and perimeter 103 mm. If the manufacture products the same paperclip with silver (P silver 10490 Km), will it be able to float in water with the same surface tension? Please show the calculation to support your answer.
