Two fluids have the same contact angle with glass. The density of fluid 1 is larger than the density of fluid 2 . (ρ1 = 1.3 ρ2) The surface tension of fluid 1 is larger than that of fluid 2. (γ1 = 1.81 γ2) Find the ratio h1/h2 of the heights to which a liquid will rise through capillary action in the same capillary tube.

1. A 1.2-mm diameter tube is inserted into an unknown liquid whose density is 960kg/m3, and it is observed that the liquid rises 5-mm in the tube, making a contact angle of 15º. Determine: (i) The surface tension of the liquid; and (ii) The capillary rise of the liquid, if the liquid is kerosene with surface tension 0.028 N/m and density is 820 kg/m3.

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.

Interface Contact angle water/glass 0° water/paraffin 107° water/silver 90° Suppose water is raised by capillary action to a height of 8.95 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 (cm)?

water Pressure vs Depth - U Shaped Tube Two Fluids 2 As shown in the figures, a U-shaped tube open to the air at both sides contain some unknown liquid. Then water (density = 1000 kg/m 3) fills the Right arm of the U-tube (there is no intermixing between the two liquids). When equilibrium is reached, h1 = 0.18 m, and height of water h2 - 0.56 m. The atmospheric pressure is 1.013x105 Pa. What is the density of the...

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...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
