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...

A closed tank is filled with water and has a 4-ft-diameter
hemispherical dome as shown in the figure below. A U-tube manometer
is connected to the tank. Determine the vertical force of the water
on the dome if the differential manometer reading is 7 ft and the
air pressure at the upper end of the manometer is 13.6 psi.
Setting up the manometer equation, I found the pressure in the
closed tank to be 2894.4 lb/ft^2, but when doing the...

7. Two capillary tubes are placed vertically in an open container of water. One tube has a diameter of 2.0 mm, and the other a diameter of 1.0 inch. In which tube will the water rise higher? 8. A sliding plate viscometer, as shown below, is used to measure the viscosity of a fluid. The plate area is 0.75 fr. A force of 1.5 x 10 lb moves the upper plate at a velocity of 10.0 ft/s. What is the...

Tank 1: Tank 2: Water h(t) h(t) Q1 (70 pts). Suppose experiments have been performed to determine the exit velocity (u) as a function of water height (h) for two different tanks. In Tank I, a smooth rounded nozzle with a diameter of a 2 cm is used whereas a square gate opening with a 2 cm side is utilized in Tank 2. The measured flow rates at different tank heights are given further below; the initial height for both...

1. Atall cylindrical tank, held above ground on stilts, is partially filled with water. (See top figure). The tank has a diameter, D. At time equal to zero, a hole of diameter d is poked in the bottom of the tank, where d<< D. Let z-0 correspond to the bottom of the tank. The initial fluid height is za. Had Use Bernoulli equation to assess the velocity of the fluid as it leaves the bottom of the tank as a...
