You spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.557 × 10-3 m3/s and the diameter of the nozzle you hold is 5.93 × 10-3 m. At what speed (m/s) does the water exit the nozzle?

U-shaped tube, open to air on both ends, contains oil. Water is poured into the left arm until the water column is 10 cm deep. What is the height of the oil column (in cm) when the system is in equilibrium? The density of oil is 801 kg/m3

Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.573 × 10–3 m³/s and the diameter of the nozzle you hold is 5.09 × 10-3 m. At what speed v does the water exit the nozzle?

Hot water with a density of 980 kg/m3 flows through a 51.2 mm diameter round pipe at 1.25 m/s.  What is the mass flow rate (in kg/s) of the water  How many significant figures should be used in the final answer?

A tank holds a large amount of water. A pipe is connected to the tank at the upper end and is open to the air at the lower end (see figure).The upper end of the pipe is h1 = 1.90-m above the ground. The lower end of the pipe is h2 = 0.570-m above the ground. The water at the upper end of the pipe has a speed of 0.640 m/s. The water at the lower end of the pipe has a speed of 8.50 m/s.What is the pressure in the water in the pipe at the upper end of the pipe?

Q16

A sealed tank containing seawater to a height of 12.0 m also contains air above the water at a gauge pressure of 3.05 atm. Water flows out from the bottom through a small hole.  Calculate the speed with which the water comes out of the tank. Express your answer in meters per second.

A student fills a tank of radius r with water to a height of h1 and pokes a small, 1.0 cm diameter hole at a distance h2 from the bottom of the tank. The water flows out of the small hole into an empty, 0.2 m-diameter container placed below the tank.  The student uses a garden hose to keep the water level in the tank at the original height.    What is the velocity of the water as it leaves the hole near the bottom of the tank?  let h1=0.55m let h2=0.12m r=0.5m 2. What is the volume flow rate of water from the garden hose into the tank? (Hint: What is the flow rate out of the tank?)  3. After 60 seconds of operation, what is the water pressure at the bottom of the container that is being used to catch the water leaving the tank?    let h=1.7m

Suppose you spray your sister with water from a garden hose. The water is supplied to the hose at a rate of 0.497×10−3 m3/s and the diameter of the nozzle you hold is 5.41×10−3 m. At what speed v does the water exit the nozzle?

To water the yard, you use a hose with a diameter of 3.6 cm. Water flows from the hose with a speed of 1.3 m/s. If you partially block the end of the hose so the effective diameter is now 0.52 cm, with what speed does water spray from the hose?
