Water is flowing in a pipe that has varying cross-sectional area throughout, and at all points the pipe is completely filled with water. At one point the cross-sectional area of the pipe is 0.07 m^2, and the velocity of the fluid is 3.50 m/s. What is the fluid velocity in the pipe where the cross sectional area is instead (a) 0.105 m^2 and (b) 0.067 m^2. (c) also calculate the volume discharged from the end of the pipe in one hour (Hint: Use volume flow rate eq. V/t=A*v and solve for V)

A large cylindrical water tank is mounted on a platform with its central axis vertical. The water levelis 3.75 m above the base of the tank, and base is 6.50 m above the ground. A small hole 2.22 mm indiameter has formed in the base of the tank. Both the hole and the top of the tank are open to the air.We can ignore air resistance and treat water as an ideal fluid with a density of 1000 kg/m3.(a) How many cubic meters of water per second is this tank losing?(b) How fast is the water from the hole moving just as it reaches the ground?

A square metal sheet 2.8 cm on a side and of negligible thickness is attached to a balance and inserted into a container of fluid. The contact angle is found to be zero, as shown in Figure a, and the balance to which the metal sheet is attached reads 0.40 N. A thin veneer of oil is then spread over the sheet, and the contact angle becomes 180", as shown in Figure b. The balance now reads 0.39 N. What is the surface tension of the fluid? N/m Need Help?

Water is flowing through a pipe with a constriction. The area of the narrow section is one-half the area of the wide section. If the velocity of the incompressible fluid is 3.2 m/s in the narrow section, then what is the velocity of the fluid in the wide section?   Multiple Choice   0.9 m/s   1.0 m/s   1.6 m/s   1.8 m/s   1.9 m/s

A container of cross-sectional area 107 cm2 contains liquid of density 1.75 g/cm3 to a height of 6.80 cm above a small hole of area 1.00 cm2 in the side. (a) Find the speed of the fluid as it leaves the hole.(b) Find the flow rate through the hole.

A water bearing pipe with circular cross section and with uniform fluid flow slowly expands in radius from 0.100 meters to 0.150 meters while increasing in elevation by 3.00 meters. If water moves at 2.00 m/s at the point where the pipe radius is 0.100 meters. How much does the pressure of the water at the new location change relative to the old location where the elevation has increased by 3.00 meters and the pipe radius has increased from 0.100 meters to 0.150 meters? Assume  = 1, 000 kg/m3 for the water in the pipe, and keep in mind that Bernoulli’s Equation.

A cubical block of wood, 10.0 cm on a side, floats at the interface between oil and water with its lower surface 1.50 cm below the interface. The density of the oil is 790 kg/m3. (a) What is the gauge pressure at the upper face of the block? (b) What is the gauge pressure at the lower face of the block? (c) What are the mass and density of the block? Oil 10.0 Wood cm 10.0 Water cm

A liquid of density 1310 kg/m³ flows steadily through a pipe of varying diameter and height. At Location 1 along the pipe, the flow speed is 9.61 m/s and the pipe diameter di is 10.1 cm. At Location 2, the pipe diameter d₂ is 17.9 cm. At Location 1, the pipe is Ay = 9.19 m higher than it is at Location 2. Ignoring viscosity, calculate the difference AP between the fluid pressure at Location 2 and the fluid pressure at Location 1. AP= Pa Location 1 z Ay Location 2 d₂

A manometer using oil (density 0.900 g/cm3) as a fluid is connected to an air tank. Suddenly the pressure in the tank increases by 7.48 mmHg. Density of mercury is 13.6 g/cm3. (A) By how much does the fluid level rise in the side of the manometer that is open to the atmosphere? ____cm (b)By how much does the fluid level rise in the side of the manometer that is open to the atmosphere if the manometer used mercury instead? ___cm
