A long capillary with an internal diameter of 0.001 m is locked vertically in 25°c water, and the water surface is 0.1 m above the top of the tube. Air bubbles are produced at the top of the tube. Bubbles have a diameter of 0.005 m.
a)Can air bubbles be attached to the top of the plate? Or will it float because of buoyancy?
b) What is the internal pressure of the largest bubble that can be attached to the top of the tube?

14) Capillary action causes water to climb up the internal walls of narrow glass tubes. Why does the water not climb so high when the glass tube is wider? A) The upper surface area is exposed to greater atmospheric pressure. B) A wider column of water weighs more. C) The water sticks better to the glass because of the greater surface area of contact. D) The greater rate of evaporation has the effect of pushing the water back downwards.

A soil sample is 10 cm in diameter and 1 m long. The sample is oriented vertically in a tube. The tube in which the soil resides is 2.5 m tall. The lower 1 m is occupied by the soil, and there is 1 m of water ponded on top of the soil. A float valve keeps the amount of water ponded on the soil at 1 m. Water drips out the bottom of the soil specimen such that the...

Combustion gases passing through a 2.3-cm-internal diameter circular tube are used to vaporize waste water at atmospheric pressure. Hot gases enter the tube at 115 kPa and 250°C at a mean velocity of 5 m/s, and leave at 150°C. If the average heat transfer coefficient is 120 W/m2 °C and the inner surface temperature of the tube is 112°C, determine the tube length. Answer in cm with two(2) decimal places.

Liquid water flows in a long pipe of internal diameter of D = 0.01 m at a mean velocity of V = 0.065 m/s. The pipe is maintained at a constant and uniform surface temperature. Assume the flow is both hydrodynamically and thermally fully developed. For simplicity, evaluate the properties of water at 300 K. Calculate the convective heat transfer coefficient of the flow inside the pipe in W/m2K?

A closed and elevated vertical cylindrical tank with diameter 2.20 m contains water to a depth of 0.900 m . A worker accidently pokes a circular hole with diameter 0.0180 m in the bottom of the tank. As the water drains from the tank, compressed air above the water in the tank maintains a gauge pressure of 5.00×103Pa at the surface of the water. Ignore any effects of viscosity. Part A Just after the hole is made, what is the...

A 3-m-internal-diameter spherical tank made of 1-cm-thick stainless steel is used to store iced water at 0°C. The tank is located outdoors at 18°C. Assume the entire steel tank to be at 0°C and thus the thermal resistance of the tank to be negligible. The heat of fusion of water at atmospheric pressure is hif = 333.7 kJ/kg. The emissivity of the outer surface of the tank is 0.75, and the convection heat transfer coefficient on the outer surface can...

Problem 2 A 30,000 litre water tank has a 4.30 m internal diameter. It has two outlet pipes, one at the base of the tank and one higher up. The distance between the two outlets means that when the water level is at the height of the upper pipe there is still 8,000 litres of water remaining in the tank for fire-fighting if needed. The top portion of the tank is used for stock drinking water. a) If the tank...
